Ferrea 96.70mm / 20 Deg / S-Flo / +1mm Radial Groove Comp Plus Intake Valve | 2003-2008 Nissan 350Z (F1563P)

2003-2008 Nissan 350Z 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 todays 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.
