BLOX Racing's high compression standard size intake valves set the standard in engine performance. Forged from durable EV8 stainless steel, these valves undergo a rigorous heat treatment process to enhance their strength. A black nitride coating is then applied, providing exceptional wear resistance and significantly reducing friction.

This black nitride coating ensures optimal protection of the valve head against wear and corrosion, while greatly minimizing friction between the valve stem and guide. The result? Reduced friction and more power output. These valves are expertly designed to maximize intake and exhaust airflow through the cylinder head, improving engine efficiency.

BLOX Racing valves also contribute to an approximate 0.3-point increase in engine compression.

Optimal Pairing: For best performance, use these valves with BLOX Racing valve springs and Ti retainers.
