lexstar16v 0 Posted January 2, 2006 I was thinking of buying a 4 branch for the valver 1.8 9190 what power difference would this make? I already have a stainless system and K+N and have those who have done it think its a worthwile mod? If not what should be my next mod to get the thing going a bit more?
