Product Description

The Brian Crower BC3601-S exhaust valve set is designed specifically for the Subaru EJ series engines, including the 2002-2009 WRX (EJ205/EJ255/EJ257) and the 2004-2009 STI (EJ257). These valves are crafted from premium-grade, heat-resistant stainless steel and feature friction-welded Stellite tips for enhanced durability under high-boost and high-RPM conditions.

Featuring an undercut stem design, these valves reduce overall weight, allowing for extended RPM potential and improved engine response. The swirl-polished finish under the head area not only enhances exhaust flow but also contributes to the overall performance gains. With a standard head diameter of 32.0 mm, these valves are a direct replacement for the OEM valves, ensuring compatibility and ease of installation.

This set includes 8 exhaust valves, covering all exhaust ports in your 4-cylinder engine. Whether you're restoring a classic WRX or building a high-performance engine, the BC3601-S valves offer reliable and efficient performance.
