Even your supercharged engine can use a little backing-up every once in a while. When the time comes for an under-hood upgrade, invest in a Holley EFI Intake Manifold. This single-plane replacement boasts port-matched upper and lower runners for reduced restrictions, and the EGR passages have been relocated to the outside for the use of larger intake ports.
Overall, you’ll enjoy greater air capacity and access to a wide-ranging power band – from as low as 2,000 RPM to a maximum of 7,000 RPM. The manifold comes with a 4150 square bore mounting flange, stands 5.5” tall in both the front and rear and ports measuring 1.89”H x 1.12”W. Your Holley EFI Intake Manifold is backed by a limited warranty.
