Product details
ALL SALES FINAL
BLOX Racing high compression standard size valves are forged from EV8 stainless steel. Each valve then undergoes a heat treatment process to increase strength then coated using black nitride to provide superior wear resistance and minimize power-robbing friction.
Black nitride provides the valve head with superior protection against wear and corrosion and greatly reduces the amount of friction between the valve stem and guide. The less friction produced the more power gained! BLOX Racing valves are specially designed to increase intake and exhaust airflow through the cylinder head.
BLOX Racing valves are specially designed to increase intake and exhaust airflow through the cylinder heard. BLOX Racing valves increase compression by approximately 0.3 points.
For best results, use with BLOX Racing valve springs and Ti retainers.
Set includes 8 x intake valves.

Before ordering
Match the full SKU, dimensions, thread or bore size, finish, vehicle application and pack quantity to the intended installation. Where an application is vehicle-specific, confirm model year, engine, transmission, body style and any stated exclusions. Universal does not mean suitable for every installation; available space, interfaces and supporting components still require checking.
Installation and use
Follow current manufacturer and vehicle service information. Performance, braking, suspension, fuel, steering and safety-related components should be installed and checked by a suitably experienced person. Confirm required companion parts, settings, clearances and local road-use requirements before installation.
