Intake

[CAyaris]

So im new to the whole motor work aspect of the yaris i work more witht he fabrication of stuff. My question is about the intake. Will it raise my gas milege. If so what are my options i have heard of Cold air intake, short ram, and than also the huge ones that go in the front grill of the car. What are pros and cons of differnt types, average prices and also where to pick them up. By the way im driving a 2008 yaris sedan

What is this. I see the air filter but what else

[big lo]

^the SRI is a very good product I haven't had any issues thus far, you can get about 15 to 20hp out that and gas you would waste a bit more, but not that much. The install itself can take 5mins or so and the sound is awesome too.

they're great for improving throttle response but isn't 15 to 20 hp very optimistic? I thought you might get that with a concurrent header and exhaust mod?

[CAyaris]

what intake will be good for gas mileage i know on my ford my full knN intake added gas mileabe

[xnamerxx]

The best intake for fuel economy is stock. If you managed to get better fuel economy with the K'N it was likely because of a change in driving style.

Simple rule the more air you let in the more fuel you will burn.
Now here is the crux of things I doubt any of the CAI will do much for you car 1-3 hp MAYBE so I highly doubt you will see any fuel economy change.

[CAyaris]

dang i thought the intake could improve

[WeeYari]

you can get about 15 to 20hp

Somebody please, please, please show me some documented proof of that type of gain. Not a hope in hell. I got 4whp out of mine in back-to-back stock vs intake dynos.

[Kaotic Lazagna]

I've gained mpgs with my K&N SRI. Nope, not a change in driving style either as I've been monitoring that long before I got an intake. Also had a SRI on my GTI when I bought it, and when I had to buy a stock intake box for smog, I actually lost mpg with the stock intake.

My friend got a K&N SRI for his Silverado, and he too got better gas mileage.

My other friend with an '09 Si found that he got better gas mileage with his AEM SRI.



The only time that you won't get better gas mileage is if you're smashing on it a lot, which a lot of people tend to do with intakes and/or exhaust work just so that they can hear it. Now, as for hp increases...well, probably not much in a Yaris. lol.

[djct_watt]

15-20HP? HAHAHHAHAHAHHAHAHHAHAHAHHAHAHAHAHHAHAHAHA.

[cali yaris]

The best intake for fuel economy is stock. If you managed to get better fuel economy with the K'N it was likely because of a change in driving style.

This is incorrect.

A drop-in air filter that uses the stock box, but allows increased airflow WILL increase your mileage.

you can get about 15 to 20hp out that

This is incorrect too. The best possible intake will net you 3-5 whp. This is proven on the dyno.

[severous01]

i gained about 3mpg with my intake. however, like mentioned above, more air means more fuel means more power.

but, you dont have to throttle down, you can always add it for economy, not power

[CAyaris]

Anyone got any links for some good ones. I want it one for looks and two for the gas mpg's. I am just looking to add a few to mpg if that or add none at all but not loose any. my new set of wheels took 40 miles off my tank. But back to what i said. Links on good airfilters.

[frownonfun]

Just get the drop-in air filter and save your money.

[CAyaris]

i am not a fan of that big black box though

[frownonfun]

i hear ya... but i'm not sure a $300 CAI is worth a few mpg.

which there is debate on whether you will gain any mpgs with a CAI anyway.

[CAyaris]

I guess the K&N is addding MPG

[Yaristeve]

I got 4whp out of mine in back-to-back stock vs intake dynos.

Any other mods or tuning to get that 4hp?

[cali yaris]

But back to what i said. Links on good airfilters.

Cold Air Intake:
AEM, Fujita, Injen, TRD, and more that I'm forgetting

Short Ram Intake:
Simota, Weapon R

SRI with box:
K&N, AFE

Drop-in Filter:
K&N, AFE

[cali yaris]

i have heard of Cold air intake, short ram, and than also the huge ones that go in the front grill of the car.

That last thing is an intercooler, not an intake. It's used for forced induction (turbocharger/supercharger).

[cdydjded]

If so what are my options i have heard of Cold air intake, short ram, and than also the huge ones that go in the front grill of the car.

This what he was talking about Garm. That FMIS (Front Mount Intake System) was actually invented by a friend of mine here in Miami in 1999. It was then sold by Arospeed from 2001-2007.

How much is that running

Short Ram Intake:
Simota, Weapon R

SRI with box:
K&N, AFE

Drop-in Filter:
K&N, AFE

Between these whata re going to be my differences between cai, short ram, sri with box, and drop in. HP difference? which is prob better gas mpg wise. and prices

[WeeYari]

Any other mods or tuning to get that 4hp?

At the time, no.

But since this was back-to-back stock vs intake dynos, things like pulleys, headers, tbs, etc would be irrelevant. Those mods would have been in place for the stock air box pull as well.

As far as mpg is concerned, I've not seen any change + or -, and I keep pretty extensive logs.

[cdydjded]

How much is that running

Check eBay, that is where they sell it now.

[CAyaris]

None on ebay for toyo just honda

[Yaristeve]

At the time, no.



Ah, cool. At 106hp, Yaris' need all the ponies you can squeeze out. Which one did you test?

[cdydjded]

None on ebay for toyo just honda

Those kits are universal. If you purchase a Honda kit you would just need to add the MAF flange.

[CAyaris]

Add a what?

[matthewai]

i got the afe on the way should be here thursday should be an easy swap ill let you know what i think from what ive heard so far about the different kinds for me personally i like it better than a cai cause of the heat box and the "louder" sound

thanks to MI, brahs :smoking:

[frownonfun]

Add a what?

i wouldn't even worry about those on ebay. you get what you pay for and although i advise against the afe/KandN aftermarket intakes (as stand alone mods) , if you are going to get one anyway just do it the right way and get it from MicroImage.

Ebay's contributions to YarisWorld = 0
MicroImage's contributions to YW = immeasurable

just sayin.

ok so between these three you left links for which are going to maybe be best for either adding mpg or keeping mpg the same

[frownonfun]

well my opinion is none of them. i saw neither an increase in power or mpgs when i had one as my very first mod. which is why i say just get a drop in (which MI also has).

if you wanna spend some worthwhile money towards saving mpgs i would get lighter wheels before a cai / sri. or take out your back seat. which that probably makes a negligible difference too but at least that's free.

but if you HAVE to get one then I'd go with the AFE.

[R2D2]

I have an AFE drop in for my wife's Rogue and they are of outstanding quality. They are cleanable and require no oil. Her oil analysis results were excellent in comparison with the stock filter so they filter well also (which is a great quality in an air filter but often overlooked).

I'm planning on getting one for the Yaris and as stated above MI has them for a good price.

[cali yaris]

hey Carlos, thanks for the correction on the front mount intake -- I didn't know about it. However, since the OP doesn't know what a MAF is, I think it's probably not his best choice.

CAyaris, get a drop-in filter and enjoy it.

Ok so with a drop in filter what is my advantage im taking your advice on this. And which one should i get from you. And whats install like

[WeeYari]

There really is no install with a drop in. It is simply a filter replacement.

Big black box located in front of battery. Two metal clips, one on left side, one on right. Flip the clips, lift up the top of box, pull out white fiber filter, drop in new one, replace top, snap clips back into place.

Done.

[CAyaris]

ok so simple now is the drop in going to help with mpg. and is modifying the black box going to mess with anything like if i but a plexi glass window on the dop of the box so u could see the new filter?

[R2D2]

That would be hard to do and would have to be perfectly air tight since it would be downstream of the filter. Unless you're one hell of a fabricator I'd choose another less complicated mod.

I took the factory snorkel off my stock air box and added a stainless mesh screen to keep he larger debris and critters out. Cost $2.50. I get cold sweats when I think of finding a nest in an air box or holes chewed through a filter. I took some pics and might do the world's simplest DIY on it. It is reversible in about 30 seconds.

[cali yaris]

If you're going to mod the airbox, you might as well buy an intake instead. The AFE intake comes with its own airbox, but no top so you can see the intake. I will disagree with anyone who posted it's not a worthwhile mod, it makes a few horsepower and you may get better mileage (assuming you don't drive differently). And it looks and sounds great.

[WeeYari]

like if i but a plexi glass window on the dop of the box so u could see the new filter?

Now you're just getting silly. :eek:

There is nothing sexy about a drop in worth showing off.

Also, a pretty much useless thing to do if for visually inspecting the filter. The plexi would be on the clean air side.

[frownonfun]

I will disagree with anyone who posted it's not a worthwhile mod, it makes a few horsepower and you may get better mileage (assuming you don't drive differently). And it looks and sounds great.

Anyone who says they can feel a 4hp difference is lying to themselves. I agree it sounds better and looks good but that's about it. Plus the guy is about to spend $170 on something that MAY get him better mileage. That seems silly to me. How long will it be before he makes up for that $170 at the pump? A year?

Look if you really wanna buy it because it looks a lot better then go for it. I'm not against spending money on cosmetics. Which if you are trying to replace the top of your stock airbox with plexi then that's probably what this really is.


EDIT: and also your first mod usually gets you kind of addicted to modding so I can see a CAI being a little more worthwhile in the long run if end up modding more things. the accumulation of a few hp, here and there, with each mod makes more of a difference, obviously.

[cali yaris]

the accumulation of a few hp, here and there, with each mod makes more of a difference, obviously.

exactly. With intake, exhaust, crank pulley and header, I made 107 whp. You can feel that.

How long will it be before he makes up for that $170 at the pump? A year?


Maybe longer. About a year and a half if he gets +2 mpg and drives 20,000 miles/year. Every year after that is saving money. Your point?

[frownonfun]

point being it doesn't make very good financial sense to spend that much on the off chance that it MIGHT save you a couple dollars a month, two years from now. put your money in a damn mutual fund or cd if you really wanna make a few bucks in a couple years.

and again, i say, if it's more for cosmetic purposes then go for it, but let's not trick ourselves into thinking a CAI makes for a good, sound financial investment.

[cali yaris]

let's not trick ourselves into thinking a CAI makes for a good, sound financial investment.

Since when is modding a Yaris in any way, shape or form a sound financial investment? I don't think anyone claimed anything close to that - you're trying to create an argument out of nothing.

If YOU don't want to spend the money on your car, don't. If, with the information and answers, he wants to, so be it.

Regardless, I think the OP's questions have been answered, yes?

[darkMINI]

The CAI's are really loud on these little cars. Just a warning. I personally use a drop-in high-flow filter with part of the bottom of the airbox removed. Still pretty loud, louder than my Dynomax exhaust.

I spend good amounts of cash on my car, but just because i havent gotten an intake or want to be different you are coming back at me it seems.

Easy Garm. I'm actually not trying to create an argument at all. And I've said on several occasions I got no problem with people spending money on their car. Why would I? It's their car. I also have no problem spending money on my own car.

In his original post, CAyaris said...

My question is about the intake. Will it raise my gas milege.

Because of that question, I assumed he was looking to up his mileage to, IDK, save money. He has repeatedly said he is looking for something that raises his mpgs. I'm merely pointing out that while this MIGHT save you miles per gallon, it isn't going to actually save you any money for a long while. So if saving money is the ultimate goal then maybe your money could be put to better use. I don't think that's all that unreasonable of a position.

However, if looks is playing into the OPs decision as well, then by all means, buy an intake. Just want him to know he probably won't actually be doing himself a favor in the "saving money" department.

On a side not, I've wasted sooo much money on the Yaris out of complete ignorance and I'm just trying to help this guy out cause he seems to know about as much as I did when I first got my car.

[frownonfun]

I don't think Garm was saying anything towards you. It's cool. He's just trying to help you out. As am I. Obviously at the end of the day, what you do to your car is up to you.

[matthewai]

just put my afe in along with the hk1 exhaust i got from jumpman (thanks again) i did it with my buddy the intake took a little longer than we thought i have an alarm and the siren for it just clears the box it was tight and we had to cut the seal other than that it's in there fine only other thing we noticed was theres no where to clip in one of the hose connectors (not sure what its called its just to the left of the MAF ahah) but i found a place to wedge it in. the exhaust was simple it is a lot louder than i expected but its cool im gonna roll with it for a while. yeah im not sure how much these 2 mods will effect mpg's but i guess its different for everyones driving style. but i do feel some difference in the pickup now its a little faster than stock i mean at least it seems that way. either way i like the way it drives now just gotta get the rear sway bar in it got to cold before to finish ahha :smoking: maybe a vid soon.....

[frownonfun]

looks good.

[matthewai]

^^^ thanks thanks gotta get this sway bar in we were looking at how it would go and didnt want to get into it

and hey i just noticed i went to look at that diy sway bar thread that cali started and the pics are gone!! what the fugg? any one know bout this

[swidd]

Taking out the seats makes it a much, much lighter car, and it accelerates much harder.

[cali yaris]

just because i havent gotten an intake or want to be different you are coming back at me it seems.

umm,, no, I was actually defending your right to do what you want. geez. LOL

@ frownonfun : we're good

@ everyone : could this thread have gone more off-topic? LOL

[RedRide]

My 2 cents.... FWIW......

I remember early on when the 7th gen Celica was released.
Someone dynoed it with the stock air fiter installed and, with it absent. .
Without the stock filter, it gained abou 5 hp in the top end and published the results.
This was basically the same gain you would get if you installed a good CAI.
So I installed a K&N filter in my Celica and called it a day. I also installed a TRD exhaust.

IMO modern air boxes are pretty efficient and little is to be gained with a CAI over a free flowing filter.

A CAI wiil give you a "WOW" factor and can be a 1st step in gaining a bit more power but, on it's own, it's not usually worth it.

[WeeYari]

Can't believe this thread has gone to 56 posts.

Well...57 now :smile:

[PumpkinSteve]

What's the difference between the AEM cold air intake and the aFe intake? Is there a general consensus as to which is better? TRD make an intake kit but it costs $$$ and says "not for highway use"...I guess it's too noisy.

[frownonfun]

NONE of the aftermarket intakes are THAT loud. And I believe they all say "not for highway use" or public road use or "intended for racing applications only".... something like that. but i'm thinking you'll be alright from a legal stand point no matter what brand you buy.

Also I don't know that there's any real difference between the brands except for the brand name itself. They all differ a little in appearance as well so I guess go with whichever is most aesthetically pleasing to your eye. But as far as performance goes, I can't imagine they are all that different.

I think of that skit from Brian Regan where he talks about what a Fridge salesman could possibly have to say.... "This keeps your food cold for $400, and this model here keeps your food cold for $500."

lol. sorry there i go again off topic.

[cali yaris]

What's the difference between the AEM cold air intake and the aFe intake?

The AFE intake is a short ram intake with a partial airbox. + is that it's easy to service the filter, - is that the iar is a little hotter there in the engine bay.

AEM (or other brand) cold air intake has piping that puts the filter in your wheel well. + is that the intake air is colder, - is that you have to remove your fender liners (and wheel) to service the filter.

[cali yaris]

"not for highway use" or "for who purposes only" has to be used on a part that has not been certified as CARB (emissions,etc.) or DOT legal. It's not related to noise -- well, it could be if it were an exhaust.

[frownonfun]

my bad i thought the AEM was a sri also.

[cali yaris]

Well, at least we all know what "iar" is. :frown:

[frownonfun]

ok now i'm confused

but anyway i was thinking maybe it would be helpful to have a sticky on intakes. just a thought.

[matthewai]

hey guys what is this unit in the middle with the blue connector?

the stock intake has a place for it to clip but the afe does not

i wedged it in between those hoses its not moving any other ideas of what to do with it or just leave it?

[malibuguy]

If i'm not mistaken, its a purge valve for the evap system

on my scion...i left the air box in place so it had a place to stay when i fabricated my intake. of course i know you guys don't have that option with intakes...

this lil' 1nz loves to scream!

[CAyaris]

So i know i ased before and i heard k n N but anyone else, have a MPG increase with any other intakes

[matthewai]

okay word yeah i dont think we have that option either but im just gonna leave it its secure enough where it is

15-20 hp is a joke. Maybe in a car that has 400hp a different intake that lets the engine breathe easier, may give that amount of performance. In our case, the 108 ponies (which there are less of at the wheels} will probably gain around 3 more ponies from the intake.
I installed a Secret Weapon R intake about month ago and my MPG hasn't changed, but I drive more aggressive now. Gassing it on long stretches sometimes to hear that 1.5L beast roar. Probably if I wouldn't do that, my MPG would have increased by a 0.7-1.5 at most.
p.s. normally I get around 30mpg.
