The FAST™ LSXR™ 102mm revolutionary new intake manifold maximizes the performance of GM LS7 engines.The LS7 may be a powerful engine platform, but when has that ever been enough for the performance enthusiast? Now GM LS manifold technology has been completely reinvented. 

The engineers at FAST™ teamed up with the airflow specialists at RHS® to develop the all-new LSXR™ 102mm Intake Manifold for raised rectangular port GM LS7 engines. Recent testing by Katech Performance produced gains of 16 horsepower and 18 ft/lbs of torque at the flywheel (versus the stock intake) on a LS7 with a mild performance cam, Big Mouth 102mm Throttle Body™ and a Killer Bee intake. Testing at the School of Automotive Machinists on a 500c.i. LSX engine with LS7 heads netted even more impressive gains of 26+ rear wheel horsepower.

Following the path chartered by the original FAST™ LSX™ Gen III Manifold, the new LSXR 102mm Intake Manifold features a removable runner, modular design that allows for easy disassembly and porting, including the ability to remove individual runners for modification. Extensive testing also led to a runner design that is longer yet much less restrictive, yielding both torque and power gains, and a larger 102mm air inlet to increase flow over the stock intake. While the LSXR™ 102mm air inlet is perfectly suited to the FAST™ Big Mouth 102mm Throttle Body™, it can also be used with stock or aftermarket 90mm or 92mm throttle bodies.

The LSXR™ is constructed from a proprietary advanced polymer material that has been burst tested to withstand 67 psi of boost. In addition, this polymer material offers a host of benefits over aluminum aftermarket intakes, including lighter weight, strength and improved heat dissipating characteristics. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows use of factory accessories without modification or clearance concerns.
