Info

These machined billet aluminum EFI intake elbows allow the use of GM LS throttle bodies on any intake manifold w/ the 4500 mounting flange. Our design incorporates an optimized transition from the throttle body to the intake plenum for maximum airflow and distribution. Dual throttle cable mounting bracket bosses are included while the 4500 flange pattern allows the elbow & throttle body to be mounted forward, sideways, or rearward. The throttle bracket is included.

Features (4) vacuum ports, MAP sensor port, machined / port matched to 4500 gasket, and 100° throttle body angle for extra hood clearance. Includes billet MAP sensor port cover, gaskets & hardware. The port design spacing will also allow a transducer to be used if a MAP sensor is not needed. The intake flange has an o-ring groove for a positive flange seal and the o-ring is included as well.
