Here’s an option for a high flow (well, at least higher flow) intake that doesn’t cost too much money. It’s simple to complete. It basically consists of drilling large holes in the factory air-box and putting a high flow filter in place of the factory filter.

Tools needed:
- K&N Filter number: 33-2360, $43
-10mm socket, wrench, and long extension
-Hole saw: I used 2 inch and 1 inch
-Drill
-Round file
-Small flat head screwdriver
http://img2.freeimagehosting.net/uploads/e5afed8aac.jpg (http://www.freeimagehosting.net/)

Steps:
1.Remove the top of the factory air-box by disconnecting the MAF and loosening the intake hose clamp. Pull out the old filter and discard.

2.Remove the two 10mm bolts holding the lower section of the air-box. The MAF wire bundle is also connected to the lower section. Disconnecting it is easy with a small flat head screwdriver.

3.Remove factory silencer tube and drill holes as you see fit in the lower section ONLY. The more holes and the larger they are mean the higher flow you’ll achieve.

4.File the holes smooth.

5.Reinstall everything with the new filter.

By opening up the factory air-box the air isn’t forced to flow through the constrictive factory silencer tube. In addition the higher flow filter decreases resistance. You can feel the result and it sounds excellent with a nice low growl. Watch Chino’s DIY intake video as it sounds identical. Also, there’s no chance of a CEL as the factory MAF mount is retained. For $43 it’s a descent intake, but probably not as good as Chino's is going to be.

Almost forgot; for those wanting to retain that factory look this is perfect because the holes are totally out of sight.

Ahhhh- the old LS1 airbox mod- but circular.

It may not be a huge gainer, but your hp/$ is better than anyone with a manufactured short ram-well, except ChinoCharles, with his fancy-assed homemade rig.

Looks like a winner!

Yeah, what can I say... I'm a baller. :rolleyes:

No, actually the first thing I did was similar to what Peter did, although mine was more "I can't take it anymore" and less "I'm going to be careful about this."

One thing... you are going to have to change that filter A LOT!

A LOT A LOT A LOT!

I drove on mine for 3 days and the filter was easily three times as dirty as it looked after 13,000 miles. Seriously, pull that thing once a week and blow it out.

And one thing... calling it a high flow intake is kind of silly. I know, I know, you said it kind of tongue-in-cheek, but the worst part about the entire intake IMO is that ribbed tube near the TB. That sucker needs to GO!

The only things that should be ribbed are condoms and supermodels.

Correct me if I'm wrong but the filter can't become dirty any faster than a CAI or a short ram intake like the one your making. In all three cases the filter is directly exposed to the elements. A tapered cone type filter like yours has more surface area, yes, but not a substantial amount leading to an increase in dirt holding compacity. Also, the ribbed rubber part is not restrictive as it's the same diameter as the throttle body. Maybe a little less smooth flowing but thats what you get for $43.00 It still improved HP; My wife noticed my car was faster today and she doesn't even know I did it.
:thumbup:

First, I have no idea why those air box filters get so dirty so fast, but they do. I've seen it! Maybe someone can explain, but honestly I see where you're coming from and it is kind of counterintuitive. If you don't believe me, drive around on that air box for a week and pull it out. You'll see what I mean.

Second, I'd bet you'll notice a difference again if you replace that little tube with something smooth. Give it a shot... it'll cost you all of 5 bucks.

PetersRedYaris
03-18-2007, 12:44 AM
I'm not heckling you... i just curious... Was it your factory filter? I did the same thing to my Tacoma (also with a K&N) and never had a problem in over 3 years. My Tacoma saw far dirtier roads than my Yaris ever will; it was taken to Mexico twice on trips down the Baja penninsula.

I actually like the rubber intake tube because I like to retain the factory position of the smaller rubber tube. Plus, the motor has so much movment with the stock engine mounts you NEED somthing with flex between it and the airbox.

ChinoCharles
03-18-2007, 12:49 AM
Yes'm, but why would that matter? If anything the K&N should filter better than that and get dirtier faster, no? Then again, maybe I'm just overestimating the amount of dirt because the stock filter is white.

... and then again, maybe I'm just <chapelle voice>smokin' rocks</chapelle voice>.

PetersRedYaris
03-18-2007, 12:55 AM
That was my thought... White filter = dirt is very visible. Then again, purple filter = harder to see dirt. Who knows? I gonna stick with it awhile and if all else fails, Buy yours!

Last thought, I'll post a pic in a month and we'll see how dirty it is.

I wonder if you could route some tubing from those holes to some fresh air? Maybe a small amount of cold air or ram air effect?

It would have been much easier to route just one hose from the silencer tube before the box was drilled... Oh well, too late now! I'm happy with it now because, provided the filter doesn't get dirty abnormally fast, I really felt a difference on my commute today.:w00t:

03-19-2007, 08:07 PM
did this a loooong time ago. does make quite the difference, but i didnt hack or swiss cheese mine like chino and peter did.. no need to imo. Two 2" holes drilled on the end of the box facing the driver side headlight is all that was needed.

Another trick is to remove (cut with a razor) the charcole filter out of the top section of the air box.

I didn't think about that, but I'm going to leave my charcoal filter in place to make sure no oil gets in to my MAF sensor. Sort of a filter for my oiled filter.

You can buy it straight from them or check to see local stores that can order it for you.

I did something similar. I removed the tuner tube, and instead of cutting several small holes, I used a cut off wheel to open the entire front of the intake box.

So facing the radiator where the cold air is comming in there is a large square hole. Sounds like a intake now.

I normally put intakes on, but I have had bad luck in the past with MAF sensors and AIT sensors not liking them on close to stock cars, more headache than its worth on a 100hp daily driver. At least it sounds good now.

Hey guys, and gals, I tried this about three weeks ago, but without the K&N Filter. I just removed the tuner tube and drilled two 2 1/8" holes on the side opposite of the tuner tube with a hole saw. Im kinda wierd in the fact that I like to take mods one step at a time to what changes and by how much. Just removing the tuner tube changed the engine sound a little, but nothing in the way of performance or mileage. After a week, I drilled the two holes in the air box. Immediatly the engine sound was in fact deeper, but over the course of several tanks of gas, I have noticed an increase in MPG. I've been getting an average of an extra 20 to 30 miles a tank before filling up again(usually 9.5 to 10 gallons). Most of my commute is 75 - 80 mph on the interstate and the rest short city driving trips, and I am by no means easy on the car. Hopefully after this friday I can get the K&N filter and see what increase that will get me, if any. Also, the stock filter is still in good shape, not overly dirty or oilly. I have just over 13,000 miles on her, so a replacement is due.

PetersRedYaris
04-11-2007, 02:39 PM
Nope, doesn't get dirty any faster than with the airbox in stock configuration. Mine has been installed over 3 weeks and 2000 miles, and the K&N fliter looks brand new. I would post a picture but it would be pointless and only encourage people to call BS on my finding claiming it's an install photo from the origional post. The filter really looks BRAND NEW. Sorry Chino, no negative results with this mod; hope you don't lose sales on your intake to this less expensive alternative.:smile:Also, hope your intake doesn't throw a CEL.:laugh:This mod never will.

ChinoCharles
04-11-2007, 02:48 PM
I did both, and I can tell you this doesn't compare to my mockup, any other aftermarket intake, or my eventual finished piece. In fact, it isn't even a performance mod... its an impulsive hack job.

Pretty much just a good way to possibly get into some warranty trouble and ruin your stock airbox. I wish I hadn't done it.

By the way, I love all the negativity on this forum lately. Why do you idiots think most of the members with any knowledge don't even post anymore? Can you guys try biting your fucking tongues?

I'm hopefully going to try this this weekend. A bit nervous about carving up the intake box, but I figure it will get replaced with a proper intake at some point. I haven't yet gone and poked around the filter so I'm not sure what this "tuner tube" is. Or where exactly I'll drill the holes... I guess either opposite the factory intake tube, or facing the front of the car. I wonder if there's a difference...?

Can't wait to hear it though!!

Yeah, it sounds nice. I doubt you'll want a proper intake after you do this as you will like the result. You will definetely feel the difference from stock and should you choose to get a proper intake later, you probably won't feel a difference from this. Wasteless money spent. I think Chino is just threatened by this mod because he did a fast hack job, regreted the workmanship, and now stands to lose sales on his EXPENSIVE intake project.

Wow, these aren't the reply's I was expecting.

For me, money is tight right now, or already allocated towards buying a new house. Car mods are far down the list, and this mod is virtually free if you have the hole bit for your drill. An aftermarket intake is on the list for me later on, and I am definetly watching chino's for results. If I can get an intake from an American for cheaper, then I will definetly buy it. I know I bought a non american car, but for the money it was the best deal. If Chino's intake works out that way, then it will be the one I buy. Until then, free mods like this are the way for me.

As for Chino's mod being a quick hack job, it may or may not have been, but at least is trying to mass produce it, not to mention help others by offering it cheaper. From the prototype pics I just saw, looks like it is coming along nicely.

Doc Zaius: The tuner tube is tube that feeds air into the airbox. When you open your hood, it will be the piece of plastic connected to the left hand side of the air filter box. This is the tube you want to remove. The holes I drilled into the air filter box where on the right hand side, and in the bottom half (the half that is bolted down). The mod probably takes 10 - 15 minutes to do, and to me is worth it. Try it out, and if you need help, send me a PM.

Check this intake out. Its only $39 shipped. It also allow you to keep your airbox stock for those trips to the dealer.

Even if you need to cut a piece off to make it fit its still worth it IMO.

.... The tuner tube is tube that feeds air into the airbox.....

So the "tuner tube" is the same thing as the "factory silencer tube"... just the tube that feeds into the intake. Got it... no problems. Thanks!

anyways, i can't believe theres so much anger in this thread. just cut the shit out of your intake box if you want, buy cc's intake(when it comes out) if you want or buy the $300 trd, fujita, aem blah blah blah...

just give ideas that can help the performance of the car and keep the rest out of the threads...:biggrin:

i read it, and i also want to know how you know it dosnt work? heh...

but anyways, you could just remove your charcoal filter, and the silencer tubing, and be done with it, skip the drilling of the holes...but thats just my opinion...because you are not going to be putting more air through the filter, without changing the rest of the piping...

Chris07LB
04-12-2007, 10:06 PM
cut hacked etc., there was no good way to fit it correctly.

Meaning just that.. I couldnt get the correct bends and still sneak a filter in there.

Remember, on the xa/xb, this intake snakes all the way past and behind the headlight.. we dont have that kind of room off our TB's, to the headlight.

Yes. Worked out good once everything was cut way down, for my classified post. IMO not worth buying for having to hack it all apart, and save the MAF adapter.

He just cut holes in the bottom half of the air filter box. Then used a low restriction air filter.

03-25-2009, 12:08 AM
yeah. on mine i took the tube off the intake box and sealed the hole it left facing the engine bay, then opened the box facing the front of the car and the fenderwell and ducted air to it with metal sheeting. then i made a aluminum box to stick over top of it to ensure it was getting cold air and nothing from the engine bay.

overkill? yes...but I was too lazy to build a mount in the appropriate sized tubing to build my own intake...and the other intakes available at the time had the MAF in the wrong location or in the wrong size of tube. screw CEL's and loosing HP.

Just to let any one know DO NOT WASTE ANY MONEY ON A K&N FILTER!! I took the air box out and hooked up the shop vac to it. My stock filter has 648 miles on it. I turned on the vac and switched the filters back and forth. The k&n pulls the rpms no diffrently than the factory air filter. The rpms stay the same between each filter telling me my factory filter breaths just as good! Taking the carcoal filter out of the lid made the biggest difference. Plus no oil in the factory filter to screw up the mafs. Just my 2cents.

Spades
03-28-2009, 07:19 PM
well, actually, K&N filters fo flow better than factory air filters. its been proven, just because you dont notice a differance doesnt mean it isnt there...we are talking about increadibly small gains, like 1 or 2 HP...i doubt your "vacuum cleaner dyno" would notice it.

and as far as oil screwing up MAF sensors, thats from people that dont know how to properly service a K&N. if you dont add enough oil, the dirt goes through the K&N, too much and it coats the MAF sensor.

the problem is idiots wait 30K+ miles to oil or service their K&N, then they clean it the wrong way, forcing water or air through the wrong side of the filter, making holes in it, then they cover it with oil till its dripping.

sorry, but reusable air filters are just like nitrous...in the right hands you have performance gains, in the wrong hands with idiots you break stuff.

03-28-2009, 11:33 PM
as far as the ear test goes, before i dropped the K&N air filter in, after i modified the air box, i ran the stock air filter. it was slightly louder than it was before I changed the box, but sounded pretty stock. after dropping the K&N in, the tone changed. now it sounds like a intake...you know the sound...the bark you get from fuel injected cars with a throttle body with little or no restriction on the air intake side.

if you dont know that sound, pop the air filter out of your car and stab the throttle.

anyway, its not just butt and ear dynos, there are flow comparason charts out there. as long as it is well kept and properly maintained, a K&N lasts longer and filters better than a paper element, which means better gas milage and better performance. it might not a be a big increase, but it is a increase none the less.

if you dont know how to service a K&N properly, I recommend paper filters.

Alright, so I just tried this. First things you need to know:

* I drive an '08 Yaris Sedan with no other mods (unless you consider amsoil and wix oil filters a mod).
* I have just over 70k miles on my Yaris, over half of which are highway miles (I drive back and forth from Georgia to Texas about four times a year).
* I typically get about 30-33 mpg in the city and 38-42 on the highway.
* I drive VERY aggressively about 80% of the time (mostly while driving in the city).

After unscrewing the bottom portion of my intake, I pulled the tube off of the intake and drilled three 1" holes into the remaining piece of the bottom portion of the intake. I drove it like this for one day with a disposable STP air filter with about 8k miles on (it didn't quite look dirty enough to replace yet). I noticed a difference in the sound and what MAY have been a small boost in HP (maybe 1-2 HP), but that may have just been the "placebo effect" from the slightly deeper, louder sound of the engine.

I threw the K&N air filter on the next day and found that the Yaris became less noisy and didn't feel like it had that same boost in HP. Please keep in mind that any difference in power from this mod went, for the most part, unnoticed when the mod was completed in its entirety.

Perhaps using disposable filters will net better results for some. Either way, I'll stick with my K&N. If nothing else, I'll be saving money on buying new air filters every couple of months.

question: in your own opinion, do you think its worth the free mod? or should i just wait and get the full intake? mine is still under warranty so i think i am either gonna just drop a k&n in the regular box or the full intake. i dont want to do anything that is not reversible for now.. although i AM gonna add cruise control:headbang:

It's worth it simply because it's free, but don't expect the kind of return you would get on a typhoon or other high-end intake. I'm happy with this setup, but I'm not looking for big power gains. Just some weekend projects, increased fuel efficiency, and maybe some extra power. I'd recommend you go for the full intake change instead of this "hack" if you're looking for power gains.

If you are worried about warranty issues, you can try throwing in the K&N filter on its own and seeing what that does (but it probably won't do much). Also.. if you wanted to, you could simply remove the tube from the bottom portion of the intake but not drill any holes. You can always snap the tube back on when it's time to visit the dealership.

I was bored, and cheap and did a custom intake today!

I wanted to avoid/minimize any permanent modifications incase i want to return the car to stock for resale or other reasons... However i did have to cut out a section of the stock foglight cover (i'll post pics of it later- but its hardly noticeable unless u kneel down and look at it from ground level).

http://i12.photobucket.com/albums/a219/FinalChapterLS/IntakeChallenge.jpg

Parts required:
~4-5' of 3"dia Flexible metal pipe ($5)
~10' of heat shield tape ($10)
4" >> 3" pipe collector ($10)
chicken wire ($10 for a huge roll) or any metal meshing to stop rocks from flying into intake snorkel
3" screw type clamp ($2)

dremel tool to cut open the fog light cover

Basicly i replaced the stock snorkel with a 3" diameter pipe that funnels air in from the front fog light. I wrapped the pipe with heat shield tape to keep as much engine heat off of it as possible. And i used the collector to make sure none of the intake charge went around the pipe from the fog light enclosure.

The job requires removing the front bumper cover, as well as the airbox to fit stuff properly etc.
