The topic has certainly been addressed here several times, but I am thinking about whether I should get a K&N 57 i KIT. Since I have at the moment only the exchange filter of K&N. So with my VR6 I was completely satisfied with the sound etc. is however a huge difference between ner 2.9er and a 1.8 he machine. Has someone installed this one? If so how has the intake noise changed? Would not like to start a discussion now, because quite a lot of people claim it is slo real for the engine (polluting etc…) I think a noticeable increase in power anyway is bullshit, I’m just talking about the sound…. Aso is there a difference in the 180 and 225 he air filters?
