LSX Intake Manifold For GEN III LS1 LS2 and LS6

New LSX™ 92mm Manifold delivers up to 20+ hp gains & added features

The new LSX™ 92mm Intake Manifold by FAST™ provides a 20+ horsepower increase over the factory LS1 intake with no loss of drivability or low rpm torque. Made from a space-age “Amodel™” polymer material that is 30 percent stronger than the stock unit, the LSX™ 92mm polymer intake avoids becoming a power robbing heat sink –ensuring the coolest, densest fuel/air charge possible for maximum horsepower output. The LSX™ also features integrated nitrous injector ports for use with direct port nitrous injection, and added runner material with witness marks to facilitate porting. In addition, the LSX™ 92mm Manifold features a patented three-piece design that allows easy access for porting and custom modifications. Looking to build some serious horsepower without tearing into your engine? The LSX™ 92mm Intake Manifold from FAST™ will make it happen!
