Description

Holley Pro-Jection intake manifolds are designed for Holley 2-barrel Pro-Jection systems. The high-rise, dual-plane manifolds are perfect for powerband ranges from idle to 6,000 rpm. With these manifolds, there is no need for manifold-to-TBI adapters. To make installation easy Holley utilizes late model alternator and A/C bracket mounting bosses and include provisions for an EGR valve and vacuum taps off of the runners. Power is made easy with Holley Pro-Jection intake manifolds.
