Torque Solution 3mm Phenolic Thermal Intake Spacers for Subaru 2002-2020 (EJ Engines) TS-SU-478-3

Fits select 2002-2020 Subaru Forester, Impreza, Legacy, and WRX STI models (EJ Engines).

Torque Solution Phenolic Thermal Intake Spacers are engineered to create a thermal barrier between the cylinder heads and the intake manifold. By reducing heat transfer, these 3mm spacers effectively lower intake air temperatures (IATs), resulting in a cooler and denser air charge for more consistent performance and improved power potential during high-performance driving.

CNC machined from high-grade phenolic material, these spacers are significantly more effective at resisting heat soak than standard metal gaskets. This is a vital modification for EJ-series engines to combat the high under-hood temperatures common in turbocharged applications. The 3mm height offers a substantial thermal break without requiring extensive modification to the intake manifold plumbing or factory mounting hardware.

• Reduces heat transfer from cylinder heads to the intake manifold
• Increases air density for improved combustion efficiency
• High-grade phenolic material provides superior thermal insulation
• Precision cut for exact fitment on Subaru EJ engine intake ports
• Manufacturer Part Number: TS-SU-478-3
