Product Description

The GSC 3041-8 exhaust valve guide set replaces the factory guides on the SR20DET with manganese bronze construction, engineered specifically to conduct heat away from the exhaust valve more effectively than stock material. This improved heat transfer is a critical factor in maintaining consistent valve temperatures and preventing premature wear under the sustained heat cycling of turbocharged operation.

Manufactured on precision CNC machining centers using the same FEA and flow simulation design process GSC applies across its valvetrain lineup, this guide set is built to hold tight tolerances for reliable valve control at high RPM. For SR20DET owners doing a head rebuild or upgrading valvetrain components to support increased boost and higher RPM ceilings, these guides are a proven, application-specific upgrade over factory guide material.
