Intake Manifold - LSXRT - 102 mm Throttle Body Flange - Rectangle Port - Multi Port - Plastic - Black - GM LS-Series - Each

Building upon the popular LSXrt intake manifold, the new LSXrt gives LS3/L92 engines more plenum volume for all-out racing. The raised throttle body location optimizes the larger, less restrictive High HP runner design, creating more power.

This LSXRT Intake Manifold gives LS3 engines with rectangle-port cylinder heads even more plenum volume for all-out racing. Best suited for high-RPM race engines, this manifold creates proven gains of 30+ horsepower over the FAST LS3 Street Manifold at high RPM. The raised 102mm throttle body location optimizes the larger, less restrictive High HP runner design, creating more power. It also clears truck drive accessories.

• 102mm inlet also works w/ OEM electronic 78/90mm or aftermarket 90/92mm throttle bodies for high flow and minimal restriction (three-bolt electronic throttle bodies require an adapter).
• Advanced polymer material is strong, lightweight and cools intake charge for enhanced power.
• Big gains in rear-wheel HP yet retains factory fitments and under-hood clearance requirements.
• Replacement runners can be purchased separately
• Designed specifically for rectangle port LS3/L92 engines in car and truck applications where hood clearance is not a concern.
• Modular design allows for easy removal and porting of intake runners.
• Proprietary precision injected polymer design offers light weight, excellent strength and lower heat soak propensity, especially compared to aluminum designs.
• Features integrated nitrous bungs and a bolt-on fit that allows the use of factory truck accessories.
• Includes our High HP runners that deliver gains of 30+ HP over standard runners.
• Feature larger plenum than the lower profile LSXr High HP intake manifold.
