An aFe cold air intake system for your turbocharged BMW is the best way to get affordable and usable power. But now aFe has decided to step it up with their all new Stage 2 Sealed intake system for the N54 twin turboed BMW's. The standard Stage 2 cold air intake has its flaws, although it comes with a heat shied it is impossible for it a true cold air intake system. aFe has found a way to get pure cold air, by enclosing the filter in a heat resistant box and pulling in air only from the front of the car. Giving you maximum power gains and a true cold air intake system! The full effect of this system cannot be felt or tested on stationary dyno and can only be fully appreciated on the wide open highway.
