Key Features

  • High-Temperature Performance: The Extreme Black valves feature a gloss black nitride finish, ensuring they perform exceptionally well under high temperatures. This unique finish helps maintain cooler operating temperatures, which significantly improves valve life.
  • Enhanced Flow: For naturally aspirated engines, these valves provide a remarkable increase in cylinder flow, leading to noticeable horsepower gains. Perfect for those looking to push their engines to the limit!
  • Superior Material: Crafted from a one-piece forged, high-temperature, high-nickel stainless steel alloy, these valves are built to withstand the demands of competitive racing.
  • CNC Precision: Each valve is CNC finished to strict tolerances, making them a reliable choice for serious racers.
  • Micro-Hardness: The black nitride treatment gives the valves a surface hardness that surpasses the base stainless steel material, ensuring durability and longevity.
  • Smoother Operation: The surface finish is smoother compared to chromed stems, resulting in reduced friction between the valve stem and guide, which minimizes power loss.

Benefits of the 20501N Valve

The Howards Cams Extreme Black Intake Valve is not just about performance; it’s about reliability and efficiency. With reduced friction thanks to the nitriding process—where the finish becomes part of the steel—these valves offer superior performance without the drawbacks of traditional coatings.
