Holley LS EFI 2x4 Mid-Rise Intake Manifolds were made after the fashion of those great dual Holley 4160 induction systems used on drag strip, Trans-Am and Lemans racers in the 1960s. With a dual-plane, equal-distribution layout, it opens the door to superior mid-range torque without compromise of power on the top-end of your LS Gen III engine equipped with LS1/LS2 cathedral port cylinder heads.
Manufactured from durable cast aluminum, it’s available for carbureted and EFI models with a power band ranging from 1,500 to 7,000 RPM. The LS engine architecture doesn’t utilize an intake-mounted water neck or distributor, and center-to-center, the carb flange measures 8.625.”
Your Holley LS EFI 2x4 Mid-Rise Intake Manifold carries a limited warranty.
