GSC Power-Division Valve Guides Subaru EJ25 SOHC

GSC Power-Division Valve Guides - Subaru EJ25 SOHC

GSC Power-Division builds its valvetrain componentry for engines that see serious track and street abuse, and these valve guides are no exception. Designed for the Subaru EJ25 SOHC engine, they use a stopper style design that locates the guide correctly in the head and keeps valve stem movement tightly controlled under sustained high RPM and forced induction loads. SKU GSC3019-8 covers the standard set of eight guides.

This listing covers intake or exhaust valve guides for the Subaru EJ25 SOHC engine. They're available as a full set of eight or as individual guides, and you can select standard size or oversized +.001" and +.003" options for heads that have been machined to accommodate worn or previously fitted guide bores. Use the variant selector on this listing page to choose the quantity and size that suits your build.

Important: a complete EJ25 SOHC engine rebuild requires two sets of eight guides — one set for the intake side and one for the exhaust side. Confirm your head's bore condition before ordering oversized guides.
