so after BMW spent thousands developing there intake system i thought id mess around with it,

basically the car turned into a lump that drove terribly and pumped out blue smoke, any reason why? as soon as the standard air box was back on she purred like a horny cougar.

i thought this set up would be perfect for a bit of extra Hp and engine noise with an engineered custom elbow for the Maf sensor and what not but no luck.

any opinions are welcomed.
