Unlock the full potential of your Subaru EJ-series engine with this set of 8 Brian Crower +1mm Over Intake Valves. Designed specifically for the EJ205, EJ255, and EJ257 platforms found in the 2002-2009 WRX and 2004-2009 STI, these valves are the perfect upgrade for high-revving, high-boost builds. With a 37mm diameter and an oversized design, they significantly improve cylinder head intake flow, allowing your engine to breathe better and produce more power.
When building a performance head, valve selection is critical. Brian Crower valves are manufactured from premium materials to ensure they maintain their integrity under the most demanding racing conditions. By increasing the intake valve size, you effectively reduce restriction, which is vital for forced induction applications where every cubic centimeter of air counts. These valves are designed to work seamlessly with upgraded valve springs and retainers for a complete valvetrain overhaul. Experience the difference in throttle response and top-end power that only precision-engineered components can provide. Find all your Subaru performance engine parts at GGCRACING.
