For the most possible flow on your LS engine, this Cathedral Port LSXRT Intake Manifold is a direct fit upgrade. These manifolds offer dramatic horsepower increases and a lightweight design for your LS.

Features and Benefits:
- Modular Design
- 25HP peak gains
- Injection molded polymer
- 102mm throttle body opening
- For GM 4.8/5.3/6.0L cathedral port truck engine and LS1

Built for race applications where hood clearance isn't a concern, the FAST LSXRT 102mm Intake Manifold yields an incredible 25 peak horsepower gain over the stock intake, on a stock 6.0L engine with a Big Mouth 102mm Throttle Body. And similar to the LSXR 102mm Intake Manifold for cars, the LSXRT features the ability to remove individual runners for modification.

The LSXRT is constructed from a proprietary precision injection molded polymer which offers many benefits, including lighter weight, greater strength and lower heat soak propensity. While it features a 102mm air inlet that was designed for the FAST Big Mouth 102mm Throttle Body, it can also be used with stock 90mm or aftermarket 92mm throttle bodies.

Other features include integrated nitrous bungs and precise bolt-on fit that permits the use of factory accessories and OEM fuel/emission connections without adjustments or clearance issues. Some GM truck models may require the FAST™ 92mm or 102mm throttle body.

Please Note: 78mm three-bolt throttle bodies require an adapter.
