Subaru EJ20, EJ25 WRX-STi Ferrea Exhaust Valve Competition Plus

Ferrea Competition Plus Valves

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.

Competition Plus Series valves for all your high boost turbocharged, supercharged and big nitrous applications
