I own a 2004 SRT4 and a 335, and a large intercooler for the SRT4 from Spearco will run you at least $800. Can you even imagine how much it will cost for our BMWs???? It has been proven that on almost all SRT4s tested with the stock turbo, it only made minimal gains. Like stated before, it will help with a turbo upgrade. I think that with xede and exhaust, this car is a freakin beast!! I would think that an intercooler sprayer would be alot more beneficary. Just my .02.
