Panic notBugger, I dont want it any louder its just right at the moment
Really tricky to say, I was planning to do some before and after data logging with vagcom but I have lent my cable to a buddy. The filter arrived and I happened to be at APS so had them fit it. It was not essential toget them to fit by the way, its a very straight forward plug n play solution and simply allows more air through than a standard oem filter, also as its still housed in the oem unit you cant see it....Ah, so that's BMC
Have you noticed an increase in perfomance, if so how much and in what way?
