Ford Racing M-9486-A53 1 Inch Phenolic EFI Intake Heat Spacer Cobra Manifold

The Ford Racing M-9486-A53 is a precision-engineered 1-inch phenolic intake manifold spacer designed specifically for Ford Performance Cobra and GT-40 intake manifolds. This high-performance component installs between the upper and lower intake manifolds to provide a thermal barrier that reduces heat transfer and lowers inlet air temperatures for increased horsepower and improved engine performance.

Key Features:

• CNC-machined from premium Westinghouse Type C phenolic material for superior heat dissipation
• 1.000-inch thickness provides optimal thermal insulation and additional valve cover clearance
• Made in the USA with improved quality construction
• Includes longer mounting bolts specifically sized for Ford Performance Cobra intake manifolds
• Complete hardware kit: 4 each 7-1/4 inch bolts and 2 each 2-3/4 inch bolts (5/16 x 18 thread) with flat washers
• Includes gaskets for proper sealing

This intake spacer reduces heat soak from the engine block, allowing cooler, denser air to enter the combustion chambers. The result is improved engine efficiency, increased timing capability with reduced detonation risk, and measurable power gains. The phenolic material is an excellent insulator that also provides additional clearance between the intake manifold and valve covers, making installation easier on modified engines.
