(16)21-4N Forged Stainless VALVES / 10+ CFM Air Flow increase over Stock
- Valve stem is 21% smoother than a chrome plated stem. This has been proven in scanning electron microscope examination.
- Smoother valve stem means less valve and valve guide friction, resulting in less wear and more power.
- Stronger and more corrosion resistant than a chrome plated valve.
- More ductile throughout the entire valve material than a valve that is not five step liquid nitrided. Proven in Rotating-Bending Fatigue Tests.
- Valve is less likely to break even if contacted by the piston.
- Improved corrosion resistance when used with exotic fuels, including nitrous.
- Our nitrating process is much cleaner than chroming. It’s better for the environment.
