1965-75 Chevy B/B w/o EGR Rectangular Port Performer RPM Air Gap Natural Finish Intake Manifold

This award winning design incorporates the same race winning technology that's been used by Edelbrock competition intakes for years.

The air-gap design features an open air space that separates the runners from hot engine oil resulting in ac ooler, more dense intake charge for more power. Performer RPM Air-Gap manifolds are ideal for street performance from idle to 5500 RPM.

Made in USA
