Ferrea Competition Plus STD Valves Honda K20 K20A K20Z K24 K24A RSX Acura Turbo

Ferrea Competition Plus Valves have built a reputation as the industry's most reliable extreme duty valve. To manufacture the valves we use special aerospace quality alloys, including the EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminates any damage to thematerial structure. The valves are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity. These valves feature avionics-quality hard chrome along with a specially applied hard tip.

The valves feature flow improvements to deliver the power needed for today’s sophisticated racing engines. These valves are available for both the traditional Domestic performance and racing engine market and the Sport Compact performance and racing market.
