More cold air ? - 29/11/2007 15:42
Having owned a Audi TT for the last year what alot of owners did to improve, and also less restrict cold air flow,without affecting the Maf etc ( and even better at no cost ! ) was to drill holes in the standard air filter box underneath so you cannot see it, the results were as good as buying a K&N Kit as tests were done, so what i am asking is have any of you guys out there done this ?
