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.
