    The LS Classic Series Tri-Power Intake Kit is designed to pay tribute to the baddest big block Corvettes of the late 60’s while using modern technology for ultimate performance. The intake kits are built around a modified single plane, dual carb aluminum intake manifold that utilizes dual 92mm, GM LS3, four bolt, throttle bodies and fuel injectors (not included) and accepts our Tri-Power style, chrome, triangular air cleaner. The kit also includes 4150 carb adapter plates, throttle body to air cleaner clamp assemblies, mounting fasteners, and cotton gauze air cleaner. The Tri-Power kit requires the use of Holley Dominator (or equivalent) ECU and harness that supports the dual drive-by-wire throttle bodies. Manifolds are available to work with Rectangular or Cathedral port LS cylinder heads.
