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.

ARP is a manufacturer of fasteners/bolts found in engines and drivelines, ranging from OEM replacement parts to specialty hardware for racing applications. ARP is the world leader in fastener technology.

The EMU Black features more built-in value than any other aftermarket ECU. It easily matches the functionality of other stand-alone management systems with multiple inputs and outputs. Unlike many other ECU systems, the EMU Black has built-in wideband lambda input (Bosch LSU 4.2, and LSU 4.9 sensors wire directly in), MAP control connector (4 bar MAP sensor on board), 2 EGT probe inputs and an input to directly connect a Flex Fuel ethanol content sensor. All of this provides greater flexibility, reduces costs and negates the requirement for external or supplemental signal conditioning control systems and the associated wiring that other management systems require.
