Ferrea 102.40mm / 25 Deg S-Flo / Trpl Groove Stk Comp Plus Intake Valve | 2001-2004 Volkswagen Jetta / 2002-2004 Volkswagen Golf (F1985P) Ferrea Racing

Competition Plus Intake Valve by Ferrea

To manufacture the valves special aerospace quality alloys were used, 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 the material 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 goal was to achieve an optimum balance of flow, velocity and efficiency in the design of these valves. As a result, these valves incorporate smoother radiuses and unique undercuts. These exclusive features are what make the Ferrea Competition Plus Valves excel in performance and reliability!

The evolution in volumetric efficiency of today‚¬™s competition engines has increased the average engine EGT. These higher Exhaust Gas Temperatures decrease the longevity of the valves as well as creating higher levels of metallurgical fatigue. These increased stress loads create an environment in the engine conducive to valve failure.

Please Note: 6 long INT valves, 6 short INT valves.
