Cosworth KK3920 High Performance Camshafts AVCS Subaru WRX STI EJ25/EJ20

Cosworth KK3920 High Performance Camshafts AVCS Subaru WRX STI EJ25/EJ20

Cosworth has been engineering camshafts for nearly 50 years. That coupled with years of innovative multi valve cylinder head design ensures our camshaft designs are the most efficient in providing maximum usable power across the widest power band. Each cam is ground from a new billet and finished using the same procedures we use in our extreme level race engines. Cosworth camshafts are the perfect compliment to our CNC Ported Big Valve Cylinder heads. Our cams are profiled to increase boost response thereby increasing engine torque and power and are fully compatible with our CNC Ported Big Valve Cylinder Heads. Sold in a matched set of four camshafts.

AVCS Camshafts

Our Subaru AVCS camshafts are available for both North American and Japan/ European applications. While the camshaft profiles we offer are the same, the cam angle triggers are significantly different between the applications. AVCS camshafts for North American applications or vehicles with electronic throttle control use a series of three slots to activate the camshaft angle sensor.
