E90 K&N Drop in Air Filter - BMW-SG

jamz · #1 (**permalink**) 03-01-2010, 02:18 PM

Hi All,

thinking of getting an air filter for my E90, have been advised by a couple of workshops to put in a K&N drop in air filter...rather than a open pod one...

any comments and advise?

Any idea where i can get this air filter at a good price?

cheers,jamz

if your ride is e90 320, a drop in filter is better than open pod.

you can get k&n filter from bvo, r2d or other workshops listed in the sponsor list.

Installed the drop-in K&N air filter for my E90 and yes there is noticeably increase in horsepower and torque.

However, my ride experienced a slight increase in fuel consumption.

i installed drop-in k&n for my e90 320 last week. can feel car more torque at low rpm, esp when moving off. car no longer feel dragging gasping but instead, moves off rather smoothly, though not as perky as jap cars yet... tink is the best liao but still got one more thing to try, i.e. change spark plugs. still undecided between bosch or volker.
