Intake Manifold, Edelbrock, RPM Air-Gap, Oldsmobile 455

Oldsmobile 455 RPM Air-Gap Intake Manifold (Non-EGR) by Edelbrock®

Air-Gap runner separation reduces heat transfer into the intake charge.

This Edelbrock® RPM Air-Gap dual-plane intake manifold is designed for Oldsmobile 455-family V8 engines. The Air-Gap design opens the area between the runners and engine valley to reduce direct heat transfer into the intake charge. Its 1,500–6,500 RPM operating range suits performance-oriented street and strip combinations. The manifold accepts a square-bore four-barrel carburetor and has no EGR provision.
