unless that car happens to be an WRX or STI and then its pretty much worthless without a tune. and even with a tune it didnt do much of anything.
it really depends on the motor and how restrictive the stock intake system is. my 2003 hyundai tiburon got 13 whp from its Cold air. (on end user dyno's) but my 1996 NA eagle talon was only supposed to gain 7 or so.
keep in mind though, that the mods won't stack. dyno numbers for an exhaust alone may give you 8hp, and a cai 10, but together you may get 11 or 12.
I'd assume the bmw intake system is designed well.
