Cold Air Intake

[yariman]

Hooked up my own cold air set-up today. I used some spare stuff I had laying around, a curved tubing piece with a flat spot that I bored a hole into for the MAF. Then added an adapter piece to accept a cone filter. It sure sounds better now. I will monitor the fuel milage and see if I notice any performance gains. If no difference then I will put the stock system back on and get a K&N when they come out.

try to find a dynometer in your area. I know a lot of them down here but we don't get yaris' till march/april

:w00t: Great to see Yaris owners putting some custom work into their own cars! Let us know how it turns out.

Here is a snap of my set-up,

[celica girl]

Looking good! I'd say it's more of a short ram intake though. Generally a cold air intake will sit a lot lower to the ground. The filter on my CAI for my 2000 celica sits right behind the fog light.

[yariman]

True enough. The air should be picked up from an out of engine bay source like the fender well or the grill etc. I did'nt think it would be too cool to cut a hole in my new fender just yet. Plus I want to see if it will have any benefits. It should, the stock filter and HC shield should be more restrictive than the cone I put on. It does feel a little lighter, could just be the sound. I'll see if I pick up any MPG in about a week.

If that device can increase not only power but also mpg and hence save fuel costs, wonderful! I always like things that can pay for themselves in the long run. Well, may be the very very long run. I am staying tuned.

[yariman]

Well as promised I did my fuel calculations with my cold air set-up and the mileage came out exactly the same as my last two tanks with the stock set-up. Difficult to tell if I gained any power without a dyno. So I put the stock system back on and will drop a K&N in when available and cut the fender side of the air box open cause I love that sound! Also cut the noise supressor out that is in behind the TB when the warranty is up. It covers half of the intake with a course wire mesh. :thumbsup:

[yariman]

O.K. I caved. Is it the power of the mind or..? I re-installed my cold air set-up, slightly modified. I swear it's got more balls verses the stock system. Once again without dynoing it or doing some before and after timed runs, I can't say for sure. However going to an open air intake system almost always increases H.P. :iono:

[why?]

I'd be amazed if that setup did not net something more than stock hp figures.

Does anyone know of an aftermarket cold air intake that's currently available for the Yaris 1.5L?

[jcove]

There are some for the Scion Xa/Xb. Shouldn't these work? I haven't tried yet, but just wondered as it's the same engine, right....?

You can browse this list at http://www.envyperformance.com/index.cfm?fuseaction=category.display&category_id=17. They say the APEXI POWER INTAKE is one of the best...

You should experiment with the air filter... See how restrictive it is compared to a K&N filter or something... Some cars see slight performance gains just from doing that...

That's a nice Backyard type deal, looks really clean. Butt dyno counts too.

the Injen SRI for Scion xA/xB should fit in that space.

[jcemitte]

Garms got an aEm for sell thats really good.


haha new record for oldest post bump :)

[sleey0]

I have the Injen (black) CAI.

Pretty cool and sound great. Not sure it does anything for power, though lol.

Look nice:)

[vwtech]

which cold air intake will give you the most power gain, I'm thinking about getting one but I dont want to waste my money if i'm only going to see like 1 hp gain. I really dont want to do exhaust either its just too loud for me as a daily driver 80+ miles.

[YarisPR]

I've been running my home-made Intake 4 years and never had a problem, except it looks ugly!!!! :bellyroll: :barf:

It's a ShortRam with a 3" wide flexible extension (Normally it is in the same place the CAIs made for the Yaris are. Also I can remove the fog light and stretch it down there cause I have an extra fog light base modded for holding the flexible extension).

The car pulled 107whp (on a mustanf dyno) with it, so DIY works :thumbsup: Now I have installed the CAI from ebay (got it for free, a friend got tire of it) and I'm about to dyno the car again so I can compare results.

Sorry for the extra dirty engine bay, but flooded streets here are in order this time of year.

Then forvet it.

Intake alone will.do.squat.

Na on our engines hardly net 5whp, and that is.with i/h/e

whats the brand of your intake on the picture?

[jcemitte]

dude you inspired me to do my own custom setup but im haveing CEL issues, yours just worked right off the bat?!?!, im so jealous!!!! and probably stupid for no figuring it out by now
