I am thinking of putting a cold air intake on my 2006 2500hd 6.6. I have a k n n drop in right now, with no issues of mas air flow. I was looking at the k n n cold air intake, 57-3057 - K&N 57 Series FIPK, Performance Intake Kit they are saying 22 hp increase, that's a lot. I have also seen a cold ram air, didn't know if that would help, and if it would look stupid. thanks for your help.
im looking for performance, so the best hp and potential fuel gain is the best for me. im not stuck on the k n n if you think I need something else, but 22 hp is a big gain
my question, what brand is recommended? knn looks good on paper but want to know what you guys are running. if there is something out there that's better that I haven't found
S&B or Banks seem to be the most popular choices for our trucks but there's no need for an intake on an LBZ unless your over the 500hp mark. Stock LBZ intakes will flow plenty of air for 500hp or more easily.
Banks is way over priced... and while yes there is no need for an intake, I still prefer one. When you spend all the money on these trucks an extra 200 for an intake is nothing.
S&B with a dry filter. You're not going to feel any difference with any of the intakes, I don't care what the dyno sheets say. Some do make the turbo sound better. Find the best filtration and there you go. If you want to feel a difference, check out EFI live
The stock LBZ filter and intake is one of the best, honestly I'd throw away that K&N drop in, pick up a Donaldson filter for your stock intake and put the money towards EGR block or delete, pcv re-route, EFI, lift pump, etc. If you really wan't an intake I'd get an S&B as stated by others in this thread.
