Holley EFI LS Single Plane Mid-Rise Intake Manifolds 300-137

Holley EFI LS single plane mid-rise intake manifolds are great for your higher horsepower engine. Featuring cast aluminum construction, these manifolds are also great for centrifugal blower, turbocharged, or NOS mild power adder applications. The efficient casting design is lightweight--11.5 lbs.--with consistent wall thickness and strong mounting flanges. The optimized runner layout and constant cross sectional area offer a broad torque curve, with the best vehicle performance from 2,500 to 7,000 rpm. The mid-rise design offers minimum carb mounting flange height--without sacrificing power--and is another plus for vehicles with minimum hood modifications. Holley EFI LS single plane mid-rise intake manifolds include zinc-plated hex head cap mounting bolts and washers, pipe plugs to block manifold vacuum and MAP sensor ports, and Viton ® O-ring cylinder head mounting flange gaskets for an OEM-style seal.Brand: Holley
