Brian Crower Subaru EJ257 - 04-07 STi 06-07 WRX Camshafts - Stage 3 - Set of 4

This is a set of Brian Crower Stage 3 camshafts specifically designed for the 2004-2007 Subaru Impreza WRX STI and 2006-2007 Subaru Impreza WRX models equipped with the EJ257 engine. These camshafts are a significant upgrade for those looking to get more out of a modified engine, focusing on increased airflow and power gains, particularly in the mid to upper RPM range.

Brian Crower is known for producing well-built engine components, and these camshafts are no exception. They are designed to work with the factory valve springs and retainers in most cases, simplifying the installation process for a performance camshaft upgrade. The Stage 3 profile is aggressive, intended for enthusiasts who have already made other modifications like upgraded turbochargers, intake, and exhaust systems. This profile is optimized to take advantage of increased boost and airflow, helping your engine breathe better and produce more power when it matters most. Expect a noticeable change in the engine's power band, with a strong pull through the higher RPMs.

When installing these camshafts, it's important to ensure your engine is in good mechanical condition. This includes checking valve springs, valve guides, and the overall health of your EJ257 engine. Because these are performance-oriented parts, they are not CARB approved and cannot be shipped to California. For optimal results, consult with a professional tuner to dial in the engine management system after installation to fully realize the potential of these camshafts.
