Features of the Howards Cams Extreme Black Intake Valve
- High-Temperature Resistance: The Extreme Black valves are made with a gloss black nitride finish, which allows them to operate cooler. This not only improves valve life but also makes them ideal for nitrous, turbo, and supercharger setups.
- Improved Cylinder Flow: For naturally aspirated engines, these valves significantly enhance cylinder flow, resulting in noticeable horsepower gains.
- Durable Construction: Crafted from a one-piece forged, high-temperature, high-nickel stainless steel alloy, these valves are built to withstand the rigors of demanding race conditions.

Benefits of Choosing the 20211N
- Micro-Hardness: The black nitride finish is harder than the stainless steel itself, providing unmatched surface hardness.
- Smoother Surface Finish: The surface finish is smoother than chromed stems, which reduces friction between the stem and guide, leading to better overall performance.
- Reduced Power Loss: The nitriding process reduces valve-guide friction, minimizing power loss and maximizing efficiency.
