Description

The GSC Power-Division 2122-8 is a set of eight intake valves designed for performance applications. These valves feature a 35mm head diameter and are constructed from 21-4N stainless steel for high heat capacity and longevity. The set includes valves with hardened or stelite wafer tips for extended life.

Engineered with advanced 3D design, these valves offer a stronger, higher-flowing head design. They are swirl polished for smoother airflow and back-cut to reduce weight, allowing for higher RPM and boost pressure. The micro-polished stems minimize drag for smoother motion.
