CAMSHAFT SET PROCAM 2JZ-GTE Non VVT-i 290-11.00

Factory camshafts prioritize smooth idle and fuel economy over low-end torque and top-end power. Upgrading your camshaft is the most effective way to modify engine behavior across the RPM range. Camshafts control the duration, lift, and overlap of intake and exhaust valve openings, improving airflow for increased horsepower and torque. This is achieved by extending valve open time, increasing opening distance, and optimizing overlap. Proper camshaft selection maximizes torque and horsepower for specific driving or racing styles. All Tomei Camshafts are CNC machined for precise fit and accurate valve lift/duration.
