Valve Features:

• Ferrea Competition Plus intake 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 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.
  
  
• Ferrea super alloy exhaust valves represent the highest level of sophistication in valve technology. These valves are designed to handle the extreme heat requirements and punishment of today’s Nitro Fuels, Supercharged, Turbocharged, Nitrous Oxide. Many Top Fuel and Funny Car teams can confirm the performance and reliability of these valves which are now available for many engine combinations including Drag Race, Time Attack, Road Race, Endurance.
  
  
• OEM Keeper/Lock Compatibility: Designed to work seamlessly with OEM triple groove keeper/lock systems. While compatible, we recommend not reusing old valve locks in performance applications to avoid the risk of material grooving.
