Cold air intake?

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

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

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

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

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

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

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

not just opens up the performance...it really kick in :)

Won't happen

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 (???)

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

sorry. when i think "sound system" i think lots of heavy gauge wire, amplifiers, subs, etc. i forgot we were talking $300...

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?

I ran into the same issue and had to do this:



Basically modify the stock depurator cap, cut the intake, fit it with couplings. No issues so far.

I'm trying so hard not to cut up my stock parts 😭

Oh I didn't... I put away the stock piece and ordered a new one to experiment, it was like $30 xD

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
