350z Ferrea Intake & Exhaust Competition Plus Stock Sized Valve Set

We have developed a specially processed high nickel-based alloy, and a unique heat-treatment process, which yields extreme heat resistance and enormous tensile strength properties, (far beyond conventional Inconel materials).

We are also reaching a fast growing segment in the Import Cars with the introduction of our New Super Alloy Import-Tuner Valve program. These valves are specially designed for use in racing engines that are subjected to extreme exhaust temperatures such as turbo, nitrous, or supercharged racing engines. No other valve on the market has been designed specifically for these applications. Once again Ferrea is setting the pace.
