Does anyone know what HP the VWR filter for the mk6 gti can flow (http://www.volkswagenracing.co.uk/parts/vwr-cold-air-intake-system-11/) as i have one fitted to my 2.0 tsi but am thinking of having a k04 kit put on it and want to know if the filter can flow enough

It will flow enough to work without problems. But on K04 you will get more power with a good induction kit

it was pretty damn expensive but is definitely doing a great job. point of note though is that the filter is physically smaller than the previous itg that i had on my leon cupra r (K04)
