I wanna put a cold air intake on my 3 but i have a couple of questions...
First of all, can u put a cold air intake on an automatic? lol, im sure this is a real dumb question but i honestly dont know much bout this stuff...
and second, i found a cold air intake made by AEM that is made for the mazda3 except all of them say "Mazda 3 2.3L Manual Transmission 2004" so could i still use that on my automatic or not?

you'll need a specific intake for an automatic tranny. I know of several people who have used a manual intake on an auto car and had problems.

check the injen website i was reading about cai's on their site and if they don't have one for the auto i am sure they could point you in the right direction

thanx you guys
