Maximum Power, Minimum Headaches!The FAST™ LSX Intake Manifold is designed as a true bolt-on part that fits under the stock hood and uses factory hardware, fuel lines, and linkages while delivering serious power gains. Made from space-age polymer plastic that is 127% lighter than aluminum and 20% stronger than the stock unit, this multipiece intake manifold shows a 20 horsepower increase on the LS1 engine and 15 horsepower on the Corvette LS6 engine with no loss of drivability or low RPM torque. Unlike aftermarket aluminum intakes, the FAST™ polymer intake avoids becoming a power-robbing heat sink. The LSX has integrated nitrous oxide injector ports and can accept a larger-than-stock (75mm) throttle body for increased fuel flow. It can be ported and is easily accessible due to its multipiece design.
