FAST LSXR HIGH HP INTAKE MANIFOLD,102MM,RECT PORT,LS3,L76,L92,L99,BLACK

Brand New Fast LSXR 102mm High Horsepower Intake Manifold for GM LS3, L76, L92, and L99 Engines (Part #146103B).

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.

The LSXR intake manifold offers several benefits over aluminum aftermarket intakes, including lighter weight, increased strength, and improved heat dissipating characteristics. Constructed from the same advanced polymer material as the LSX 92mm intake manifold, the LSXR features a 102mm air inlet that is perfectly suited to the FAST Big Mouth 102mm throttle body. However, 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.

Note: If using OEM fuel rails and injectors part #146025-KIT is required for proper installation.

Compatible with:

• GM LS3, L76, L92, and L99 Engines
