A 36mm Intake Valve Built for Consistent Sealing

GSC's intake valve is precision-machined to a 36mm head diameter in the STD size, giving you an exact-fit replacement or upgrade option for the EJ205/EJ207/EJ257 platform. The chrome-polished stem reduces friction as the valve moves through the guide, which matters for both long-term wear and consistent valve action at higher RPM. That polished finish isn't just cosmetic, it's a real functional detail that affects how the valve performs under sustained use. It's a straightforward improvement that's easy to appreciate once it's installed.

Sold Individually for Flexible Builds

This valve is sold individually rather than as a matched set, giving you the flexibility to replace just the valves that actually need attention rather than buying a full set unnecessarily. That's particularly useful when doing a partial head rebuild or replacing a single damaged valve. Confirm the exact quantity and head size you need for your specific build before ordering. That combination of durability and performance is what makes it worth the upgrade.
