IAT sensor?
 

Where is this located at.

I have a 05 mazda 3

on your airbox just after the filter.

it's part of your MAF sensor...like matty said...part of the airbox...look for the sensor attached to it

ok, thanks for the help

Nice 3 by the way, welcome to the club if it hasn't been said before.

I like the foglamp placement.

Thanks, mine didnt come with fogs, so i had to put them in. and there was no place for them in the normal spots haha.

i like your paint.

Stock paint FTW!

Kind of funny though, I swapped my stock grille out for a Mazda 3 one, and you already had that one, but still swapped it out, haha.

haha , you want it? ive got it in the garage. but its black. dont know what use you would have for it anyways..

hey quick question. if i got some aftermarket plugs and wires, what would that do for my performance? anything?

Not really, plugs wouldn't really do a thing, and wires just prevent misfire, it's just to carry electricity.

For performance, think of your car as a giant air pump. You want mods that bring air from the front to the back as fast as possible. Headers, downpipe, intake, turbo, exhaust, etc.

Anything else is pretty much just for comfort and looks.

Edit: of course, weight reduction helps a bunch too.

ive got the intake and exaust, now i need headers and a downpipe. but i dont trust OBX, i want vibrant headers, but its more than twice as much. i dont know if it would be worth it.

Check Corksport, I know their downpipe is supposed to be good. As for headers, check out ProtegeGarage, or PM Gary (kargoboy) to see if he has any for your car. Thunder headers are supposed to be pretty good.

By the way, do your fogs actually do anything while driving, or does that mesh keep most of the light inside the grille?

they definately work. it doesnt really make a difference. but its kinda cool because all the things you drive by have a diamond light pattern. but as for the front theyre solid beams, they work good.
