EVIL ENERGY Small Block Chevy Dual Plane Air-Gap Small Gap Intake Manifold

Small Block Chevy Air-Gap Small Gap Intake Manifold for Street/Track Builds

The EVIL ENERGY Small Block Chevy dual plane air-gap small gap intake manifold is built for carbureted SBC owners who want stronger upper-RPM breathing without moving to a narrow race-only intake. Its air-gap runner layout, small gap open type plenum, and 4500-6500+ RPM range make it a focused option for compatible street/track Small Block Chevy builds.

Small Gap Open Plenum Design

The small gap between the two planes lets the plenum sides share airflow demand at higher engine speed. This helps the manifold keep the street-friendly character of a dual plane design while adding more upper-range support for engines that are driven harder.

Air-Gap Layout for Cooler Intake Charge Behavior

The air-gap structure separates the runners from direct engine valley heat, helping reduce heat transfer into the intake charge area. For drivers comparing an SBC intake manifold, SBC air gap intake manifold, or Small Block Chevy intake manifold, this design is aimed at balanced street/track performance rather than basic replacement use.

Air-Gap SBC Intake Manifold Performance Details

• 4500-6500+ RPM High-Performance Range: Built for SBC drivers seeking stronger upper-RPM pull and horsepower support in street/track combinations.
• Small Gap Plenum Balance: The partially connected plenum helps both planes share airflow demand under higher load, supporting more even pressure recovery.
• Dual Plane Street Manners: The two-plane foundation helps preserve practical carburetor signal and usable response for vehicles that still see street duty.
• Air-Gap Heat Isolation: The air-gap runner structure helps limit heat transfer from the engine valley into the intake charge.
• Cast Aluminum Construction: The intake manifold cast aluminum body provides a durable performance platform for classic Small Block Chevy upgrades.
