GSC bronze valve guides for the Subaru EJ series engines are machined from C67410 manganese bronze on precision CNC turning centers. Bronze guides offer greater lubricity and improved heat transfer over OEM cast iron guides. When running stainless steel valves at high rpm and at high power levels bronze guides are an essential upgrade. These guides are shaped to maximize airflow through the port rather than simply copying the stock design. The depth stopper ensures easy installation to the correct height.
