BLOX Racing's high compression standard size intake valves are a pinnacle of engineering, forged from the robust EV8 stainless steel. Each valve is subjected to a heat treatment process to bolster its strength, followed by a black nitride coating. This coating not only provides superior wear resistance but also significantly reduces friction, crucial for preventing power loss.

The black nitride treatment ensures outstanding protection against wear and corrosion while dramatically reducing friction between the valve stem and guide. Less friction translates to increased power output. These valves are designed to enhance intake and exhaust airflow through the cylinder head, optimizing engine performance.

BLOX Racing valves also help in boosting engine compression by approximately 0.3 points.

Recommended for Optimal Performance: Use in conjunction with BLOX Racing valve springs and Ti retainers.
