GSC P-D Subaru EJ205/EJ207/EJ257 Chrome Polished Exhaust Valve - 33mm Head (+1mm) - Set of 50

GSC Power Division is known for making well-built engine components for performance applications. This set of 50 exhaust valves is specifically made for Subaru EJ205, EJ207, and EJ257 engines. These valves feature a 33mm head size, which is 1mm larger than stock, offering an improved flow path for exhaust gases. This can help your engine breathe better, especially in modified or high-performance setups.

Each valve in this set is constructed from durable materials and has a chrome-polished finish. This finish helps reduce friction as the valve moves within the cylinder head, contributing to smoother operation and potentially longer valve life. The +1mm oversized head design is a common modification for tuners looking to maximize airflow and performance from these popular Subaru boxer engines. Having a full set of 50 ensures you have enough valves for a complete engine rebuild or build project.

When rebuilding or modifying your Subaru EJ engine, using high-quality internal components like these exhaust valves is crucial for reliability and performance. Ensure you have all the necessary supporting components for installation, such as valve springs, retainers, and seals, which are typically sold separately.
