GM LS1 FAB INTAKE MANIFOLD W/FUEL R

Designed for LS1, LS2 & LS6 cylinder heads with cathedral intake ports, this Racing Power Company intake manifold is made from 6061 aluminum and TIG welded for strength and durability. It suits most high-performance applications, from naturally aspirated setups to forced induction. The manifold features a 102mm GM 4-bolt throttle body mounting flange, threaded vacuum ports, and an LS3 style MAP sensor port. The kit includes billet fuel rails, a steel braided crossover fuel line, vacuum port fittings, mounting hardware, and o-ring gaskets (manifold and throttle body). Please note that the throttle body is not included. It is designed to work with stock cathedral port LS heads with OEM port locations; consult with the head manufacturer for fitment if using aftermarket heads.
