A camshaft controls the timed delivery of the air/fuel mixture in an internal combustion engine, thus it is the key to true high performance. These camshafts are factory spec OEM units found in the Integra Type-R. Depending on your application and engine component setup, these camshafts can give an excellent power and torque increase from 3000rpm to redline maintaining a smooth powerband and idle. These camshafts are for use in the DOHC VTEC series engines only. Whenever performance camshafts are installed, we recommend the use of stiffer high-performance valve springs to eliminate the chance of valve float and a B&M Command Flo fuel pressure regulator kit to adjust the fuel accordingly to compensate for the increase in air intake. Each sold seperately. Please specify intake or exhaust when ordering. Japan Spec camshafts feature a higher lift and longer duration.
