Has anybody got any real experience with a cold air intake? BMW says that their CAI will give you a couple or HP and AFe says they will give you up to 17 HP. I know that advertising pays but BMW always quotes low numbers and everybody else high numbers. I've got a Dinan 3 with 361 HP so it's pretty healthy but a few more horses wouldn't hurt. For the money BMW's isn't worthwhile but is anybody elses?
i think your intercooler takes care of cooling your air temps.
Just because aFe says it will give more doesnt mean it will. You can bet the BMW CAI was designed by better engineers with a more thorough understanding of the car and the engine. I would get the BMW CAI, especially since the BMW CAI will help resale value, aFe CAI will hurt the value.

you will gain 17hp from the afe if your current air filter is a solid block of dirt and you have a dead rat in the intake tube
BMW performance intake FTW
Life is like a car wash and I'm on a bicycle.
You won't believe how much power I made when I switched from stock air filter to cai. I made readily 452 whp from stock 230 hp.
Sound will be fuller though.
