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.

• 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.
