Cosworth has been engineering camshafts for nearly 50 years. That coupled with years of innovative multi valve cylinder head design ensures Cosworth's 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 Cosworth uses in their extreme level race engines.
 
Cosworth cams are profiled to increase boost response thereby increasing engine torque and power and are fully compatible with Cosworth CNC Ported Big Valve Cylinder Heads.
 
Sold in a matched set of four camshafts.
 


                     AVCS Camshafts

            North American          Japan/ European
 
Cosworth's Subaru AVCS camshafts are available for both North American and Japan/ European applications. While the camshaft profiles Cosworth offers 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. Japan/European applications use four raised triggers to activate the sensor.
 
If in doubt, check your original camshafts before ordering.
