They are 4010s and I had to hand cut the bear claw to fit. I did the intake with TORS first with a tune and it made a big difference. Shortly after I bought pistons and cams from Lush and a pipe system from Paul Bryant. That was huge power but did cost the coin. Let me know if I can offer any help. Pm me anytime you like.
