GSC Power-Division S1 Billet Camshafts 268/266 for 2004-2007 Subaru Impreza WRX STI (EJ255/EJ257)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2004-2007 Subaru Impreza WRX STI models equipped with the USDM EJ255 or EJ257 engine and intake-only AVCS.
GSC Power-Division S1 billet camshafts are engineered for street-driven Subaru engines looking for a broader powerband and increased top-end performance without sacrificing low-end drivability. These cams are machined from new, high-quality billet steel cores rather than reground factory units, ensuring precise tolerances and superior material integrity under high-load conditions.
The S1 profile features a 268-degree intake and 266-degree exhaust duration, specifically optimized to work with the factory USDM intake AVCS (Active Valve Control System). This setup provides a significant increase in horsepower and torque through the mid-to-high RPM range while maintaining a smooth idle and excellent vacuum characteristics for daily driving.
- Intake Duration: 268°
- Exhaust Duration: 266°
- Material: High-strength billet steel
- Compatible with factory intake AVCS
- Designed for USDM EJ255 and EJ257 engines
- Manufacturer Part Number: 7025S1
