Made from space-age polymer plastic, the new FAST™ LSX multi-piece component intake manifold shows a 20 horsepower increase on the General Motors LS1 engine and 15 horsepower on the Corvette LS6 engine, with no loss of drivability or low rpm torque. Best of all, the FAST™ space-age plastic polymer intake is 30 percent stronger than the stock polymer unit. Unlike aftermarket aluminum intakes, the FAST™ polymer intake avoids becoming a power robbing heat sink. The LSX comes with integrated nitrous oxide injector ports. In addition, the LSX manifold has the capability to be ported and is easily accessible as a result of the multi-piece design. This intake manifold will require an LS2-style fuel rail. If you have an LS1/LS6 vehicle, it will require the use of FAST #146021-KIT fuel rail kit. Intake gaskets are not included with the manifold.
