He said (and Cobb actually backs this up on their website) that the stock intake is super restrictive (Cobb says the most restrictive they've seen) and a simple CAI adds 15-20 rwhp.
He said the stock MS3 which traps around 100-101 mph does much better when it can breathe and a CAI alone allows it to run equal or slightly ahead of cars like the BMW 335i that trap in the 105 mph range.

IDK, but if that's the case it would give a stock 335i a good run.
But I find it hard to believe.
