Torque Solution 8mm Phenolic Thermal Intake Spacer for Select Subaru 2002-2020 (EJ Engines) TS-SU-478-8

Fits select 2002-2020 Subaru Impreza WRX/STI, Forester XT, Legacy GT, and WRX STI models with EJ engines.

The Torque Solution 8mm Phenolic Thermal Intake Spacer is engineered to reduce intake manifold temperatures by creating a critical thermal barrier between the cylinder heads and the intake manifold. Constructed from high-grade phenolic material, these spacers effectively minimize heat soak, ensuring a cooler, denser air charge for more consistent power delivery and improved combustion efficiency.

Beyond its thermal insulation properties, the 8mm thickness adds volume to the intake runners, which can help optimize airflow and mid-range torque. This is a direct-fit solution for enthusiasts looking to maintain lower intake air temperatures (IATs) during spirited driving or on-track sessions.
