Cosworth Camshafts S2 Grind Subaru STI 2004-2007

Cosworth has been engineering camshafts for nearly 50 years. That coupled with years of innovative multi valve cylinder head design ensures our camshaft designs or the most efficient in providing maximum usable power across the widest power band. Each cam is ground from a new chill cast 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 Subaru EJ25 cams are profiled to increase boost response thereby increasing engine torque and power and are fully compatible with the Subaru STI AVCS.
