HKS Camshaft EJ207 264 EX

This HKS 22002-AF005 exhaust camshaft is specifically designed for the Subaru EJ207 engine, commonly found in Japanese Domestic Market (JDM) Subaru Impreza WRX STI models from 2000-2007 (and potentially 1999-2000 models with the 2.0L Turbo H4 engine). It features a duration of 264°, a valve lift of 9.6mm, and a designed valve timing of 112° to optimize exhaust gas flow and engine performance.

The camshaft is a precision-engineered engine component, intended for performance enthusiasts looking to tune their EJ207 engine. While exact performance gains were not specified, camshaft upgrades typically contribute to improved horsepower and torque by altering valve timing and lift.

Installation of camshafts generally requires specialized tools and expertise. It is recommended for experienced mechanics or those with a strong understanding of engine assembly. Factory parts like valve springs and retainers may need to be inspected or upgraded in conjunction with a performance camshaft. This part is designed for the EJ207 engine and is not compatible with the 2.5L EJ257 engine found in some later model Subaru Impreza WRX STI vehicles, particularly those in the US market. The product is marked as discontinued by the manufacturer.

This camshaft is a direct fit for the EJ207 engine within the GDB chassis code. Always verify compatibility with your specific vehicle's engine code and model year before purchase.
