Description

Upgrade cooling efficiency while adding a premium finishing touch to your EJ engine build.

The Torque Solution High Flow Billet Thermostat Housing for Subaru EJ Engines replaces the restrictive factory housing with a precision-machined, high-flow design that improves coolant efficiency and engine bay aesthetics. CNC-machined from 6061-T6 billet aluminum and finished in black anodize, this housing delivers both performance and durability.

The enlarged internal bore and smooth tapered transition promote more efficient coolant flow, helping reduce turbulence and supporting more consistent operating temperatures—especially important for modified or hard-driven EJ engines. Whether you're refreshing your cooling system or finishing off a performance build, this is a functional upgrade that looks right at home.

Replaces OEM Subaru Part Numbers:
11060AA060, 11060AA061

Install Note:
