2010, 2011, 2012, 2013 Chevrolet Camaro SS LS3 & L99 FAST LSXR High Performance Intake Manifold

** Tune for Low-End or Top-End Power! **

FAST™ engineers teamed up with airflow specialists at RHS™ to develop a polymer intake manifold for rectangular port GM L92/LS3 engines. Testing on a stock LS3 engine with a Big Mouth 102mm Throttle Body™ produced gains of 14+ horsepower and 11+ ft/lbs of torque at the flywheel over the stock intake. The LSXR™ 102mm Intake Manifold features a three-piece modular design that allows easy disassembly and porting. Extensive testing led to a runner design that is longer and less restrictive and gives the user the ability to remove individual runners from the manifold for modification.

Constructed from the same advanced polymer material as the LSX™ 92mm Intake Manifold, the LSXR™ offers a host of benefits over aluminum aftermarket intakes, including lighter weight, increased strength and improved heat dissipating characteristics. While the LSXR™ features a 102mm air inlet that 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. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows the use of factory accessories without modification or clearance concerns.

Optional FAST 146025-KIT LSXR LS3/LS7 Fuel Injector Spacers:
These FAST LSXR LS3/LS7 fuel injector spacers are designed to extend your short OEM fuel injectors to the same length as the longer-style injectors. These kits include spacers and O-rings.

Optional Nick Williams 102mm Throttle Body:
Nick Williams 102mm LS-series throttle bodies are precision CNC machined for unmatched quality and beauty. This incredible throttle body is a perfect match for your FAST manifold.

FAST LS7 CASE STUDY: FAST™ LSXR™102mm Intake Manifold for LS7: 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. Quick Summary Product: FAST™ LSXR™ 102mm Intake Manifold for LS7 Part Number: #146202 Features & Benefits: - Intake manifold designed for LS7 raised rectangle port heads. - Gains of 16+ RWHP on stock displacement engines & 26+ RWHP on larger cubic inch engines. - 3-piece modular design with removable runners for easy disassembly & porting. - The 102mm throttle body intake diameter works with 90, 92 or 102mm bodies for high flow with minimum restriction. - Advanced polymer material is strong, lightweight, easy to modify and keeps intake charge cool for power enhancement.
