Halltech's C5 Venom™ II is the second generation intake. It utilizes the stock Mass Air Flow sensor for easy installation and seamless smooth response on the street or at the track. Starting with the Super Bee II 15" wide Halltech filter with a built in velocity stack flange, the actual changes to the mold design have increased flow to the throttle body. The filter is designed by Halltech but made by K&N exclusively for Halltech's Super Bee II. The bridge is also made from the new KB II mold which dynoed over 13 HP on the Katech Engine Dyno. Fits 2001-2004 Corvette C5 LS1 and LS6. The MAF sensor shown is not included, but provides a laminar flow screen with higher flow than the stock LS1 screen. Use your stock MAF, elbow for the A.I.R. pump and wire harness.
