YAMAHA YZF 400 1998 - 1999 WRF 400 1998 - 2000 STEEL OUTER INTAKE VALVE

Vertex Stainless Steel One-Piece Intake Valve

Enhance the reliability and performance of your four-stroke engine with the Vertex stainless steel outer intake valve. Designed as a direct, high-performance upgrade, this component addresses the common limitations of factory two-piece valves, providing a robust solution for riders and engine builders who demand longevity.

Each valve is precision-engineered from high-quality stainless steel using a one-piece construction method. This design eliminates the structural weak points often found in multi-piece valves, significantly reducing the risk of failure during high-demand operation.

Key Features

• One-Piece Construction: Removes the risks associated with multi-piece valve designs for increased durability.
• Advanced Coating: Precision machined with a chromium-nitride coating to provide superior protection against tip erosion and premature stem or seat wear.
• Engineered for Longevity: Designed to meet or exceed original equipment specifications, ensuring consistent performance in demanding conditions.
• Optimized Performance: Ideal for engine rebuilds where reliability and thermal resistance are top priorities.

By upgrading to Vertex stainless steel intake valves, you ensure your engine remains protected against the fatigue often experienced by standard factory components. These valves are an essential choice for maintaining engine health and achieving optimal performance during intensive use.
