This has been tested, you get no horsepower from intake without a tune. With stage 1 tune, only one available for our X3, you get ~5 hp, with stage 2 on say 335 or I think X1 you can get 10. FYI, fastest x1 has BMS intake, he's running near 11's in 1/4 mile. Unless your drive is almost all start and stop traffic, then once the car is cruising the temp by intake in engine bay isn't all that hot and certainly won't be heat soaking. The intake is $200, Ive got a tune for last year, I'm gonna buy one and try it myself, if it sucks then I'm out $200, if not then I get a slightly faster car with potentially much better sound. We'll see. I've got an early version of jb tune that I can change boost on, comes with 3.5 boost, some have had success with 4 and 4.5, may play around with that too.
