Ford Racing M-9486-A52 Cobra 1/2 Inch EFI Intake Heat Spacer

The Ford Racing M-9486-A52 Cobra intake plenum spacer is precision CNC-machined from high-quality Westinghouse Type C phenolic material, engineered to deliver improved engine performance through effective heat dissipation. This 1/2-inch thick spacer installs between the upper and lower intake manifold sections, creating a thermal barrier that helps reduce heat transfer from the lower intake to the upper plenum.

Key Features:

• Precision CNC-machined from Westinghouse Type C phenolic material for superior heat insulation
• 1/2-inch thickness provides optimal spacing for heat dissipation and improved airflow
• Designed specifically for Ford Cobra EFI intake systems
• Reduces intake air temperature for denser air charge and increased power
• Complete mounting hardware included for direct installation
• Helps reduce heat soak during performance driving conditions

By creating an insulating barrier between the intake manifold sections, this spacer helps maintain cooler intake air temperatures, which translates to improved volumetric efficiency and power output. The phenolic material resists heat transfer while providing excellent durability and dimensional stability under high-temperature conditions.
