How many times has this topic come up, which induction kit is the best? So sorry to bring it up again but, I am so confused! The general concesus seems to be that the GSR twincone kits and CDA are the way to go. However I notice a number of people on the forum use KandN, surely they are not that bad if all these people use them. I currently have a KandN 57i on my sei mpi and its definately better than the original airbox - and I don't mean just in the noise stakes! But, is the GSR conciderably better, I need a lot of people to tell me if it is, so I make the jump and buy one. Is it worth all the extra money? I have heard about poor quality from KandN but, I clean my regularly and it seems fine so any feedback would be great. Cheers.
