is it possible to use the stock airbox w/BMW filters with your plenum and tune?
Also if I am already running all bolt ons including headers will you provide me with a tune that goes with those mods?
VERY interested in your intake after seeing TDonnells write up.
Not worried about heat soak, okay, maybe a little haha,
It makes some sense having the boxes since it pressurizes the air into the plenum. BMW didn't spend so much time developing those boxes for nothing.
Yeah, I hear where you are coming from. Especially with scoops I think there could be some power gained at high speed. How much however, is a good question.
Exactly, I wouldn't mind using the large BMC filters though, the scoops could still push air into those areas, I would just imagine it'd be even better if the air was pressurized before hitting the plenum, for a better combustion.
Its funny, but I have an engineer friend who swears (this just came to my attention) that the way the air flows up over the hood at 70mph+ on these cars renders the scoops ineffective as advertised. They don't do any harm though.
