2004-2007 Subaru WRX/STI PROCAM 10.4mm Exhaust Camshaft by Tomei

Countless hours of research and development is performed in order to complete a set of cams that meets the TOMEI standard. The end result is a high-quality product that produces effective and reliable results. Every cam is engineered on super precise CNC machines and incorporates magnesium phosphate coating to prevent direct contact with other valvetrain components.

Additionally, every cam lobe is treated with a "wavy groove" to promote oil lubrication and prevent cam locking. PONCAM TOMEI PONCAM Camshafts provide the smoothest idle, acceleration, and installation. No modifications are needed to the valvetrain when installing a set of TOMEI PONCAM Camshafts and the performance is smooth from zero to the top end.

The TOMEI PONCAM Camshafts are perfect for the tuner looking for no-nonsense, reliable street performance. PROCAM TOMEI PROCAM Camshafts are the highest performing camshafts offered. Aggressive grinds and massive powers are the results of testing and super high precision grinding. TOMEI PROCAM Camshafts may require additional valvetrain modifications, but the results are well worth it. The TOMEI PROCAM Camshaft is the best of the best from TOMEI.
