DIY: Intake Installation

[redyaris]

Hello all. Redyaris here serving the Yarisworld community yet again with an (easy) DIY! I have the word easy in parentheses because depending on your mechanical skills this could be easy or a bit difficult for some.

Tools needed: metric or SAE wrench set, hex key set, utility knife, phillips and flathead screwdrivers, time and patience!

Time Allowance: Took me 2 hours from start to finish. (Those more mechanically inclined probably will take an hour).

Many here have either already installed an intake system or are planning to in the future. I purchased a Weapon R Dragon Intake system from the fine vendor wesellcarparts.com available on Yarisworld. What a deal ($109 shipped!). As you know, im cheap. This is a basic intake system that delivers on what it promises from a reliable manufacturer with a lot of experience in developing intake systems.

This DIY is for the newbies or anyone who has never attempted to do this.

A modified or aftermarket intake has many advantages over the OEM airbox: among these are increased airflow to the engine boosting horsepower (a wee tiny bit), cooler engine running temperature (some here have reported a 10 degree drop), and a more agressive engine sound from underhood!!!!:biggrin:

NOTE: You may choose to do the steps in an order different than I did. Don't bitch me out if you didn't do yours like mine.:thumbsup:

NOTE: Your results may be different than mine were. I am not responsible for your installation.

NOTE: If you receive a check engine light after installation (CEL) you did something wrong. DO NOT continue to run your engine if you receive this warning!!!!

Part 1: Deconstruction of OEM Airbox

1. Disconnect your negative battery cable as a precaution and to reset the Engine Control Unit (ECU).

2. Undo the OEM top airbox metal clamps to loosen the airbox. Remove airbox filter. Observe the dirt! Yucky.

3. Using phillips head screwdriver, unscrew the two small screws holding the Mass Air Flow connector (MAF) from the airbox. Also using flathead screwdriver pry the MAF wiring plastic anchors from the airbox.

4. Once the MAF connector and wiring is free from the airbox pull the MAF sensor carefully from inside the airbox. You may have to wiggle it a bit to get it out. Dont knock this little thing around it costs a lot of money and can cause you a check engine light upon reinsertion. Be nice to it. :smile:

5. Disconnect the PVC hose from the airbox inlet pipe. To do this pinch the hose clamp and move it back away from the clamping point then pull the hose off the airbox. Tug it good and it will free.

6. With all hoses and wiring free from the airbox, go to the clamp that connect the airbox hose to the throttle body (TB = silver metal part). Using a phillips head screwdriver untighten the screw holding the clamp. When loose, move the clamp around and away from the clamping location.

7. Using a flathead screwdriver gently pry the airbox hose off of the throttle body pipe. Use some force here as that thing is TIGHT on the pipe. After removing airbox clean TB pipe area.

8. Remove the upper airbox component from the engine compartment.

9. The lower airbox component is secured by two bolts. Using a wrench remove these bolts then remove lower airbox from engine compartment.

This completes part 1

Part 2: Installation of Intake System

10. Insert assembled intake into engine compartment to test fit. Do not secure clamps at this time. Insert intake silicon connector to throttle body to test connection. This fitment must be tight with no vacuum loss (air escaping from connection). Adjust if neccessary.

11. Once fitment is correct tighten two supplied metal clamps to intake throttle body silicone connector.

12. Tighten two supplied metal clamps to intake filter element end.

13. Remove 4 nuts from engine cover and remove it. This is done to access the PVC hose coming off engine block.

14. Remove PVC hose from engine block by squeezing the clamp on hose and
moving back from clamp point. Tug the hose and it will come off for removal.

15. Measure new PVC replacement hose supplied with intake for fitment. The new hose will connect using the OEM factory clamps at both ends of engine block and intake pipe.

16. Cut the black tape that connects PVC hose to other hose in engine compartment. This will free hose to be removed from engine compartment.

17. Cut new supplied PVC hose with utility knife after test fitment. Ensure you have not cut the supplied pipe too short to fit on intake pipe from engine block.

18. Connect PVC pipe at both ends using factory clamps. Replace engine cover and tighten nuts.

19. Recheck all clamps, hose connections for tightness.

20. Start engine, let idle for 5 or 10 minutes for ECU to adjust to intake. Check for any Check Engine Lights (CEL). If you get this response turn engine off and recheck all hose mounts and clamp mounts.

NOTE: The intake I received came with a chrome mounting bracket shown in the pics. I have not used it yet but am planning to as an intake can bounce around a bit depending on vehicle motion and engine RPMs.

That's it. Enjoy the more aggressive sound coming from your engine bay.

Nice write up....

[steved]

Nice install!!

How much?

How does the car feel?

[AlphaFox]

nice writeup. a few notes:
I didnt need to use the supplied breather tube, the stock one was long enough.

the bracket can be inserted under the hoseclamp on the filter end. you will notice its hooked and curved at one end, stick this under the clamp. the other end can be secured onto a bolt, I used one that was next to the headlight area in the front left corner of the car.

good luck!

[redyaris]

Yes Alpha the OEM hose was almost nearly long enough. I started not to use the supplied hose.

I havent noticed any difference in engine 'feel' and a slight difference in sound from the engine mainly because my exhaust is drowning it out! LOLOL.

And the price? Currently I dont think $109 shipped can be beat for a legitimate name brand intake....plus it came with an extra filter and filter cleaner!

NOTE: You need to lightly oil the filter prior to installation. Forgot to mention that. Its also recommended you clean the filter every 3000 miles.

[nsmitchell]

Excellent write up!

I like the intake, but why is the pipe so freakin long? I would think the shorter the better...:iono: Possibly to get cooler air from the headlight hole???

[jetaimejsc]

nice write up, simple to, i might just get this kind of intake, where did you get it, did you get it from a sponsor here?

[redyaris]

I agree. The pipe is a little long. The length puts the filter almost on top of the headlamp unit. And they call it 'short ram'!
I got the intake from the sponsor classified section from wesellcarparts.com

Fast shipping with tracking number, low price, no hassle. Thats my idea of a great sponsor.

BTW, I moved the hoses that previously sat on top of the OEM airbox under the new intake. It secures them more and helps to show off the intake better.

[nsmitchell]

I wonder what a few minutes with a hacksaw could do??? You would definately want to use the bracket at that point and it wouldn't rattle anymore.

[07typeS]

Yea I just purchased and installed this intake as well. I agree it is pretty long and takes a little bit of manuevering to get it in there right. I used the mounting back to keep it wedged in there a little better and it seems to do the job. I also left the stock hose intact because when I take it to the dealers for my oil changes I will putting the stock intake back on and switching it when they are done.

But very nice write up.

And I agree, Maybe a litle work with the hacksaw to shorten it up just a bit....

[Pavel Olavich]

Before you guys go through the trouble of installing an in-take system, did it ever occur to you that most of those systems on a Yaris will add a pitiful amount of HP? What, 1,2,4 HP? Before you spent your hard earned $$ on that thing, did you research this? And I don't mean by reading claims from the maker of such devices.....

I would be surprised if any one having a new in-take, if they get more then 5 HP from it....My buddy just did same for his 2007 Mazda Speed3 and the before and after Dyno showed an increase of just 6 HP....the idiot didn't do his research....after $600 installed he gained a whopping 6 HP!!!!

Save your money gents!

So if there is no increase in performance, why the hell did you do it?!? :laugh: :laugh: :laugh: :thumbdown: :thumbdown:

[eTiMaGo]

1. 5HP gain out of a 300HP engine would be ridiculous, but remember our weedwacker engines are not exactly all that powerful... 5HP is close to a 5% increase, which is not too bad, and small increases here and there will add up
2. This particular intake is $109 shipped, it's a decent chunk of change but not exactly a huge waste of money. As for your friend with his $600 intake, that's quite a different story :wink:
3. Looks better than the stock plastic box, sounds better too

If the guy's happy with the results, that's all that should matter, right?

[tiksman]

Nice Man!!!! You just wont stop moddin. I got the AEM that goes over the rail and into the bumper area. It was a minor hp gain and a lot of rev up noise which is ok by me.

[Nigal]

Wish I would have had this DIY a month ago when I fumbled my way through putting mine in. I picked this intake for the price but also because it's the only one that shows actual dino results for in a Yaris with a 5hp gain. Can I feel 5hp? Probably not. Do I think I can feel 5hp? Youbetcha! I think it's a psychological thing that makes our brains make the connection between: more sound = more power. Every little bit helps though.

[slvryaris]

Very nice. I believe this is the first DIY I have seen for the intake. Was it just me or was the bolts at the bottom of the air box a pain in the @$$ to get out well at least down to.

Thanks for your ever positive outlook Olavich. I'll bet you go around telling kids there's no Santa Claus dont you?

FYI I wasn't looking for horsepower out of this 'in-take'....and I think I said that any power gain would be a 'wee tiny' amount.

BTW Pavel accept this site as my free gift to you: http://www.freewebs.com/steven200/

My pleasure to provide this DIY for the Yaris. Sorry I didnt provide even more detail. I like to give back to this site which has provided me so much and has become an addiction for me.

Hopefully this will assist with future intakers.

The airbox bottom bolts were not a problem...Just had a long extension on my wrench, which the ladies love.:thumbup:

I hade about 2' of extentions on my socket and it still sucked donkey balls.

Hey, if you want to live in the land of dillusion, that's your choice. It just seems really immature to add a toy to your car that probably gains 1 or 2 HP, just so you can have a "better" sound?

Back when you were 8, you added a card to your bike, so that when it drags over the spokes it made a cool motorcycle like sound. Well, it seems that you're still in that mind frame today.

You and everyone else knows damned well that your intake does effectively NOTHING for performance on your car. What a f--king waste of time, resources, and money!

Grow. Up.

[Astroman]

What about your mind frame paval? Your posts reek of negativity.

The land of 'dillusion'? Can you explain that one? LOLOLOLOL. Give up while you're still behind Olavich.

And you still suck...hard.:evil:

RedYaris, how many HP have you gained?

[redyaris]

RedYaris, how many HP have you gained?

Don't know and don't care. How many times do I need to answer this.

[Pavel Olavich]

Don't know and don't care. How many times do I need to answer this.


Zero times. But don't you think before you add mods, you should determine what the benefit is? I mean, even if it cost you just $10, if the mod don't do shit to improve performance, or MPG, woudln't it occur to you to not make the mod if all it does is change the intake sound? That's the point I'm trying to make....if the "benefit" is just in your head....ah, heck....why do I try to reason with a young guy like you?

Hey, I know.....add a tail pipe insert to your Yaris....just a few bucks, and I heard on the internet you'll gain 5 HP! :eyebulge: Get the kind that flairs into two pipes, then you can claim "dual exhaust"! lol

[YarisTom73]

We modify our vehicles simply because we want to. When I pull into my dealership coming to work every day, I see a handful of white sedans exactly like mine. Perhaps it is only my perceived youthful angst that propels it, but the feeling is always present that I would like mine to look different. So, would a few hundred bucks for sticky graphics or shiny wheels enhance my vehicle in any mechanical way? Nope. But I'd enjoy it because it was different. I need no other reason. Therefore, I feel that if the intake makes a cool sound and nothing else, who cares? It differentiates that vehicle from the next. If it gains .01 HP, so what?
I say let the lemmings jump off the cliff if they like; they will be smiling on the way down, when you, Pavel, are still bitter.

:thumbsup:

Pavel who pissed in your corn flakes? You need anger management classes badly.

People modify they cars to be different from others, it's kind of like putting their personality into the car. Even if a modification looks stupid or does absolutely nothing in performance to the car does not give you the reason to tell someone off. Just say "it's not for me" or something else intelligent, or even better don't comment at all.

RedYaris great install and hope you enjoy it.

[redyaris]

why do I try to reason with a young guy like you?

Thanks for the compliment Pavel...nearing 43 I do feel quite young. Just proves once again your mouth is bigger than your foot.

[REM]

How easy is it to change/clean the filter? I had one on my last car and I had to pop the liner above my driver side wheel to change the filter, way too much work. This doesn't seem that bad, but still it seems like it could be trouble.

[redyaris]

Filter cleaning is recommended every 3K miles. I dont look forward to taking it off, cleaning and re-oiling it thats for sure.

[uncleyaris]

Another great write up!! Motivates others that they can do these things. Must sound nice up front!! Can't wait to see the pics for your HU, hint hint!!

[redyaris]

Thanks Uncle...this is why I continue to produce these DIYs to help others who might never attempt such a mod.

Thanks for the compliment Pavel...nearing 43 I do feel quite young. Just proves once again your mouth is bigger than your foot.

You're in my age group? Wow...all the guys I know my age have better things to do with their time then to add a useless CAI intake on a Yaris, of all vehicles, especially if the benefit is zero. Na, I'm not bitter...I just find it most amazing RedYaris, I would expect a teenager to do what you did...hey, you're entitled to your own dillusion, and all the power to you...wait! All the 0.53 HP to you! :headbang:

Now guys please do let me know of any and all mods that will either add MPG, or power or both, and I mean more then 10HP or 2-3 more MPG....those are the ones I'm interested in...

[uncleyaris]

Pavel, give it up. Everything you like others may not like and vice versa, be respectfull!!

[QTvDWGbziqGjbkb]

Nic3 tutorial redyaris. Kudos!

I'm in the process of installing one in my Vitz myself. I like the nice sound of the Flowmaster muffler, CAI and Turbo combined. I just drive up to 60 mph... no more; so hp are not relevant to me. Besides the faster you drive the more gasoline you burn and the more tickets you get ;) .

Anyway, thank you again for spending some time writing these DIY's. 5 stars for it!

I went with the AEM and it's my favorite mod to date.

How was the AEM install? Was it a semi-long 'short-ram' also? LOLOLOL

[puetato89]

R/Y.. would you like to help me put on mine since i live in orlando as well :rolleyes: and yes i do know the thread is old :tongue:

[Chupacabra]

Pavel,
Why are you taking somebody's decision to uselessly modify their car so personally? You are going about it all wrong...calling him/her childish etc. Let people do what they want....they don't need to explain it to you. They earn their own money and can spend it however they please. With that said, I do agree with you in regards to a CAI being a completely and totally useless modification on this car. $100 can better be spent IMHO but....I am not going to bad mouth or call somebody childish for doing what they want with their own money. I actually wouldn't be surprised if HP across the rev range was decreased due to placement of the filter. Toyota engineered the intake air horn for the best pressure zone.

[puetato89]

+1 but thats probably why hes banned

[THEBROWNSTONEKING]

Thanks for the post man, not what I was looking for but definitly helps alot, I bought a filter but not the intake system, so I need to get the filter box out to install this performance filter in, can u help me thru this? the pics definitly helped aswell since I have a Yaris aswell

[eTiMaGo]

it would be good if you can post a picture of what you have so we can understand better.

When you take out the white paper filter from the stock box, at the bottom you can see two screws, when you take them off, you can take off the whole stock filter box...

[Nakachi]

Thanks Cool DIY TIPS

[oge90]

tengo una pregunta y un problema que hace dias me esta calentando la cabeza ....instale el filtro conico con un adaptador para el maf y enciendo el motor y se detiene en un segundo y no entiendo porque

[oge90]

porfavor ayudeneme

[268i]

Hi everyone,

I've tried installing a pod filter on my Yaris (1.3l auto) this weekend but have been having some problems.

I use a spectre 8705 MAF housing,a silicone pipe reducer from 3" to fit the yaris orginal pipe and basic 3" pod from local autoparts store.

I start the car up and it idles at around 2500rpm, few seconds later the rpm's drop until under 1000rpm and the car shakes and the engine turns off. (Feels a lot like stalling a manual) Happens in about 10 seconds.

At the beginning I thought it was a faulty pod (restricting air flow) and left just the pipe on without the pod but the same thing occurred. Trying a different MAF sensor from my other toyota but the same thing happened. MAF sensor is positioned almost the same position as it was with the airbox.

Anyone had this happen before?
