LSx Swap Kits

Spectre’s universal LSx plenum kits are fabricated from high quality polished aluminum sheet metal, and are designed for Chevrolet LS engine swaps where space in the front of the engine compartment is limited. The over the top design mounts the plenum over the top of the intake manifold and draws air in from the back of the engine compartment. These kits require 4.25 inches minimum clearance between the throttle body and the fan or radiator in front of the engine and 7.25 inches minimum from centerline of the throttle body to the underside of the hood.
