Cosworth Full Camshaft Set 278-274 Subaru STI EJ25 JDM Euro Spec 2.5L

We have 1 full set, brand new, camshafts. Set includes 2 Intake camshafts with duration of 278 degrees and 2 Exhaust Camshafts with duration of 274 degrees. This camshaft set is for JDM Euro spec STI's that have a throttle cable instead of a drive-by wire.

Cosworth has been engineering camshafts for nearly 50 years. That coupled with years of innovative multi-valve cylinder head design ensures their 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 their CNC Ported Big Valve Cylinder heads. Cosworth's cams are profiled to increase boost response thereby increasing engine torque and power and are fully compatible with the CNC Ported Big Valve Cylinder Heads.
