The Edelbrock Performer RPM Air-Gap Oldsmobile 455 intake manifold is intended for aggressive street/strip big-block Olds applications. Designed to optimize horsepower production from 1500 to 6500 rpm, this manifold will perform best with engines that have an aggressive camshaft profile that will take advantage of the increased flow this manifold can provide. This manifold features our popular Air-Gap design that separates the runners from the hot engine oil, resulting in a cooler, denser air charge for more power. This manifold is compatible with stock heads, but has been designed to work with our RPM cylinder heads 350-60519 for optimal performance. Not compatible with EGR or spread-bore carburetors.

Since founder Vic Edelbrock Sr. began building performance intake manifolds in 1938, Edelbrock has grown into one of the most trusted names in American high-performance parts, from carburetors and intake manifolds to cylinder heads, crate engines, and EFI systems. JEGS has spent decades supplying Edelbrock components to racers, engine builders, and street enthusiasts, backing this extensive lineup with in-house technical support, fast shipping, and a Price Match Guarantee so you can choose proven Edelbrock parts with confidence.

Dual-Plane Intakes with the Powerful Air-Gap Design

Edelbrock has brought race-inspired technology to the street, again! The RPM Air-Gap is a dual-plane intake manifold with a dropped plenum divider that separates the intake runners from the hot engine oil in the lifter valley. This provides a cooler, denser air/fuel charge for more power.

Edelbrock RPM Air-Gap Manifolds elevate street engine performance by using a race-inspired design that keeps your intake runners separated from the hot engine oil. The unique dropped plenum divider delivers a cooler, denser air/fuel mixture for increased power and efficiency—especially under spirited driving scenarios.

Constructed for serious enthusiasts, these manifolds employ a dual-plane layout that promotes strong throttle response and efficient air distribution across cylinders in the 1,500–6,500 RPM range. The air-gap design ensures cooler intake temperatures, translating to crisper performance and minimized heat soak during extended runs.

Here’s how the RPM Air-Gap stands out:

Race-Bred Cooling: The open air space under the plenum keeps the incoming charge cooler, maintaining air density and combating power-robbing heat accumulation—especially noticeable at elevated RPMs.
Proven Performance: Real-world dyno testing shows the Air-Gap manifold delivers slightly higher peak horsepower and torque compared to standard RPM models—packing a subtle but meaningful advantage.
Street-Savvy Engineering: Designed for everyday drivability as well as occasional track duty, it blends the power gains of performance tuning with the refinement needed for daily use.

For those outfitting a edelbrock air gap intake manifold, this product brings advanced thermal management and impressive multi-RPM performance gains. Enthusiasts looking for top-tier rpm air gap sbc upgrades get both competitive edge and street-ready reliability. And when considering an rpm air gap solution, you'll appreciate the blend of engineering finesse and proven performance delivery Edelbrock is known for.

Upgrade your small-block Chevy with a manifold that balances power and precision—where lower temperatures meet higher output.
