Kibblewhite "White Diamond" Inconel Exhaust Valves for Yamaha YXZ [(2016-21) 80-81316K]

We have used these valves in high-performance turbo motors for years and proven their quality and performance. This is an OEM replacement valve standard OEM sizer oversize +1 mm. Complete set of 6 exhaust valves.

One-Piece-Forged "Super Alloy" Inconel® 751

• Retains all mechanical properties at elevated temperatures
• Something only superalloys can do
• Maintains corrosion resistance at elevated temperatures
• Something only superalloys can do
• High Nickel content for superior strength and toughness
• A must for Forced Induction or Nitrous
• Inconel® is classified as a "Super Alloy," meaning that it is designed to survive under the most extreme temperatures and pressures, where other valves will begin to burn, corrode, or completely fail. This is the material of choice for high output engines running turbos, superchargers, nitromethane, or nitrous.

White Diamond™ Stainless steel exhaust valves

• Available in stock and +1mm sizes
• Valves are impregnated by a unique German process to a depth of .002, with a surface build-up of .0002.
• This White Diamond process improves wear properties, reduces friction, and provides corrosion resistance and wear superior to chrome and nickel electrolysis plating.
• Each valve is designed using Finite Element Analysis software, and profiles are tested on our computerized flow bench. White Diamond Valves are lightweight, solid, and one-piece forgings with profiles that provide excellent flow characteristics.
