Just about to get my '00 S4 Avant and wondered if air filters will make any difference whatsoever to my car's performance, economy etc..?

Any help well received.

Cheers
 
so you dont reckon a K&N performance air filter is worth the bother??

let us know!

cheers!
 
waste of time the only way you will really benefit is if you have huge BHP and want to allow gasses to flow faster!
 
only reason to get an air open air filter of some kind is to hear the turbo and recirculating valve louder, and IMO the only way to go if you get an aftermarket filter is get a long track filter which takes it to the front bumper, only for the engine bling though
