Just wondering what people would recommend as far as a high flow air filter goes for my 325ti?
Green? K&N? Pipercross? BMC??
Some other brand i'm not aware of??
have a BMC CDA air filter - carbon fibre sealed unit type
is it worth fitting it to my 323 ?
have read i wont gain any extra bhp but will improve throttle response - so is it worth it to fit it
Thanx
