Hey man, just read your guide on ATF change and noticed you're from the Pittsburgh area. I am thinking about having my fluid changed as well and would really love to know the shop you took it to. Thanks man.
Dude, wait till May when I do my cross country trip. You will crap yourself seeing how much gear I can get into an E46 and still make it look clean inside.
I think that with or without scoops the airflow going from the front duct into the airbox (that little elbow) is already filled with as much air possible and it doesn't make a difference. Just my opinion
