BLOX Racing's High Compression Standard Size Valves are precision-forged from EV8 stainless steel, embodying strength and durability. Each valve undergoes a rigorous heat treatment process and is coated with black nitride, significantly enhancing wear resistance and reducing friction that robs power.

The black nitride coating ensures superior protection against wear and corrosion, drastically reducing friction between the valve stem and guide. This reduction in friction not only conserves power but also contributes to improved engine efficiency. These valves are meticulously designed to amplify intake and exhaust airflow through the cylinder head, thereby optimizing engine performance.

BLOX Racing's valves also contribute to a compression increase of approximately 0.3 points. To achieve optimal performance, pairing these valves with BLOX Racing valve springs and Ti retainers is recommended.

This set includes 8 exhaust valves, offering a complete upgrade solution.
