To top off your LS engine, these Intake Manifolds are a direct fit upgrade on your LS3 engine. They provide reliable performance, and room for a 102mm throttle body for high horsepower applications. The polymer construction offers maximum flow and durability.

Features and Benefits:
- 102mm throttle body opening
- Advanced polymer construction
- Modular design
- Improve heat dissipating

FAST engineers teamed up with airflow specialists at RHS to develop polymer intake manifolds for GM LS-based engines. Testing on a near-stock LS7 engine with a Big Mouth 102mm Throttle Body produced gains of 16+ horsepower and 26+ rear wheel horsepower on a 500ci engine.

Constructed from the same advanced polymer material as the original FAST 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.

The LSXR features a 102mm air inlet that is perfectly suited to the FAST Big Mouth 102mm Throttle Body. Other features include integrated nitrous bungs and perfect bolt-on fitment that allow the use of factory accessories without modification or clearance concerns.

Now available for LS3, L76, L92, and L99 rectangle port applications is a High Horsepower version of the LSXR Intake Manifold. With shorter and straighter runners than the original LSXR, the High HP intake can make up to 20+ more horsepower than the original.
