Cold air intake?

[Yaris709]

Anyone on here running a cold air intake? Wondering if it's worth the money on the yaris or just a waste

[Bluevitz-rs]

It makes a difference. But it also makes for some better induction noise.

[invader166]

Unless you plan on doing the wholle induction system (intake, throttle, and manifold) than I it's kind of a waste.

Unless of course you want extra induction noise with no real extra power. :laugh:

[tarkus]

The Yaris' stock intake is already placed to take in cooler air. So that's not really an issue. On my Yaris, I've just put in a drop-in replacement AfE filter, which provides higher airflow and is also washable. Then I removed the carbon filter from the air box as well. It gives the car a little more go, and a bit more growl.

[rabbito]

just like tarkus said..stock box is already cool enough...go with throttle body or manifold...had the intake but took them off, no real gain...i went with 1zz throttle body with custom piping thay matches the exact size of t.b and intake box

It's absolutely hilarious on a supercharged 1NZ with a 1ZZ throttle body. Lots of loud supercharger noises and some serious HP gains to boot. On an otherwise stock engine, you may see a few HP gained.

[ecampos]

I have a cold air intake on my Yaris, I think it mostly just adds kind of a growl throttle noise. Performance gains are minimal if any.

If you want to get a mod and actually feel a slight difference go with exhaust headers, you'll feel that more than the CAI.

I have a K&N typhoon air intake. I can say that you a very very nice sound with the vvti. No more drop between gear shift and a better acceleration as the car is more responsive.https://uploads.tapatalk-cdn.com/20170427/1def82c89cba471e9817c94bb1c44672.jpghttps://uploads.tapatalk-cdn.com/20170427/9491e980f290476d91a2d643b61f7b8e.jpg

you shaved 2 seconds off 0-62mph with an intake and a muffler? that's the most amazing thing i've heard this week! i've seen people pay $5,000 to accomplish this, who knew all they needed was an intake and a muffler....

I don't even think my 2zr swap netted me 2 seconds....

You better check your timing device :) 2 sec sounds very optimistic !

It's the feeling when someone spent like 320$ on a filter and he is trying to convince himself that he did a good choice :p

I mean common 300$ for a filter? I searched it on amazon yesterday and that's the price.
Really with this amount of money you can do so maaaany better things:
•put a spoiler
•put a good sound system with touchscreen and amp + new speakers
•convert the cloth seats to leather by a professional workshop
And much more things
They don't change the power, but neither the filter does

its worth it especially if you plan on some day getting a header and full exhaust (not just a muffler section)

[Yaris709]

Will probably go with an intake soon and sometime in the future maybe a header will be installed. Probably wait for the manifold to leak and replace it with a header then

[SirDigby]

sound system and leather adds weight=slows vehicle down.
spoiler adds drag=slows vehicle down
i have an injen intake. i think it was $130
injen flow tunes intake tube=speeds vehicle up (maybe .2 second faster 0-62)
k&n flow tune (???)

Install a 1zz (Corolla/ Matrix) throttle body to really open up the performance.

Wait you really think that a sound system will slow down your car?? [emoji23] about 0.001 sec?
As I said they don't give any speed upgrade but neither filter gives any speed bump.

Ok time for me to jack this thread. I ordered an intake for my 2010 yaris 3dr and the air sensor does not bolt up at all! Very far off on the bolt holes. Yes I bought a cheap intake but for those who are on the facebook page and remember Aimee and her 3rd gen "laboon" she had the same problem with her AFE intake. Now we are talking $50 intake vs a $300 intake so I can't call quality here, there must be something else at play. Anyone run into this issue? Does our car have 2 different model air sensors?

[DiCaprio]

Stock 0-60 time is in the 10 sec range. I seriously doubt that an intake did anything.

It all comes down to the launch and conditions.
I've done a before and after test with new tires, lightweight alloys and air intake.
The car was stock before.

Before with winter tires and stock air intake the best i could do was 11.1 sec
After with new sticky summer tires and aftermarket air intake the best i could do was 11.3 sec.

So after i did the mods my 0-62 times were worse than before.
So i guess my winter tires stick well enough to put the power down and it all comes down to the launch and your shifting.
You can scrape off some time with good shifting.

But with a bad launch my times are always in the 12-13 sec range.

My engine is the 1.3l 2SZ-FE

I know it seems simple to me, but are you sure you were mounting the MAF in the correct direction. It only goes in one way because the holes are offset.

110% sure. There's a 4mm difference in mounting hole spacing and even the hole for the sensor to go in is 1mm too small

The biggest difference that comes into play between your time and mine is that our engines are different. I have the 1NZ, and even with a wheel/tire setup that is heavier than stock and an axleback I've been able to get a 10 second range 0-60 with everything stock otherwise.

Sticky tires can take away performance of a car also. They have a higher rolling resistance, which basically means that you need more energy to move them than a tire with lower rolling resistance tires such as snow tires or energy conserving tires. With the 2SZ being limited on power already as is, sticky tires can negatively impact the performance.

Honestly, just by adding an intake and exhaust isn't going to make any car much faster (there are exceptions). It will however make your car louder, and if that is what floats your boat then :thumbup:

I have the exact same issue with an intake I ordered. It sucks haha and I can't return it now cause I had it forgot about. Have to find a way to rig it up to work somehow. I could file out the maf sensor hole and try to find a way to secure the sensor down tight. The maf sensor is literally less than a mm to big but screw holes are off quote a bit.

[Yaris709]

Bump if anyone could point me in the right direction to get my intake to work

[heeroyuy01195]

If the screw holes are that far off it might be better to drill new holes and tap them if there's enough material. If not then I would say try and find a different intake or at least a section with a MAF mount. I think someone had one posted in the classifieds section on the forum. Can you put up a picture or two of the hole alignment?

[Bluevitz-rs]

Does the sensor fit in the hole? The screws aren't esencial, they're just there to locate its orientation and keep it in place.

Well if you have tools to make the hole bigger and get the sensor in there you can just seal it with a little silicone and zip ties.

Second start was 2 sputters and some pops. Third start I gave it a ton of gas while it sputtered and she fired right up. Burnt up the water in about a minute with white smoke and a nasty smell then she was ready to roll the next 60 miles with zero issues!

I gave up on my intake couldn't get nothing to work and after hacking it up and grinding/filing it. Definitely non-returnable now LOL I did go with a k&n drop in filter and gonna do the airbox mod. See how that works out for me

Yes you do gain some mileage with a CAI. As long as you don't drive more aggressively to hear the intake growl.

[JimKellyfan]

I did the K & N filter and the OBD throttle plate spacer with some 80 mm bolts off amazon. feel like I got 3-5 in the butt dyno. More smooth and less useless windup in passing gear too. exhaust manifold from OBD is next with 1/2 inch bigger bores running out.

[JimKellyfan]

I put on the OBX header and feel a bit more oomph. Pretty happy with my poor man upgrades so far. You do hear the clattery engine in the am a bit more, but no smoke and actually better fuel mileage with the header. I run it hard, and was getting 32-34, now I am getting 35-36, so more oomph and mileage, well worth the 200 bucks the header, not so sure on the spacer. Looking to do something with the intake/throttle body/poor mans colder air than stock upgrade next. while putting in the K&N helped, bein this close to the beach makes me leave in that carbon filter (after the main air filter piece) in case crap gets beyond the stock filter.

[williew2]

I put K&N typhoon kit on and am suffering from initial down low acceleration, it great after 3000rpm, but from stand still it's a slug, have headers and free flow exhaust. any ideas how to improve it.
