yeah, I saw a couple of them and they are pretty sick, and plus I love the new car smell. And if I get that promotion, I'll be in a position I've never been in, where I can actually afford a new car...so if I'm gonna get one...might as well get the best (=

 

if you wanna reset the ecu just unplug battery terminals comletly and repale.

 

resetting the computer to re-learn the car isn't really needed for something as small as an air filter. if you were doing something much bigger...a larger turbo, fuel rail, whatever...it may not be a terrible idea, but am air filter isn't going to make a big enough change to bother it.
