Comp Cams FAST LSX Polymer Intake Manifold for LS1/LS6

Comp Cams/ FAST polymer composite intakes have shown a 20 hp increase on the GM LS1 engine and a 15 hp increase on the GM Corvette LS6 engine, with no loss of drivability or low-rpm torque. Best of all, the FAST material is approximately 30 percent stronger than the stock piece. Also, unlike aftermarket aluminum intakes, these composite units avoid power-robbing heat soak. If that wasn't enough of a reason to swap out your intake to the Comp intake, they also come with integrated nitrous ports. Application: GM LS1 & LS6 Engines
