SIR testing?

[BMW RACER]

Thanks for the words of encouragement. At this point I'm going for it and then decide after some track time. I don't think fitment should be too hard. I've found a source for aluminum tubing: www.burnsstainless.com

I'm thinking of getting some 3" tubing in straight and curved sections. Then cutting and welding it kind of like how people fabricate exhaust systems.

Routing wise, I'm thinking 45 deg out of the air mass sensor, down through the hole under the left headlight, kind of like most aftermarket "cold air systems" Then making a right turn that will run in front of the radiator over to the area behind the right fog light. I'll keep you posted on the results.

The hoses shouldn't be too tough I'm thinking 3" tubing, 4mm difference should be workable. Once again I'll get back to you on that.

careful with where you put that air filter john. read the itcs carefully. i think the location you are thinking of is outside the engine compt and may be illegal. that hole under the headlight could be defined as the limit of the engine compt.
