apologies, I should have said "aftermarket filter",
I'm not looking for power gains ATM and don't expect them with a filter. Was just wanting some more induction noise coz ATM the car sounds very mute, especially coming from a Type R. Was thinking a K & N filter or the likes, will add a fair amount of noise I'd guess and should be similar levels of quality as OEM VW.
Wheres the cheapest place to get one?
