Why Are KMP Valves Leading The Way In The Aftermarket?
Because we match OEM material and specification using an expensive but necessary material called Inconel.
KMP’s Inconel valves are engineered with the same premium material specified by the OEM: Inconel 751 – a superalloy trusted in motorsport, aerospace, and high-performance engines where failure isn’t an option.
Many valves being offered by others in the aftermarket do not contain Inconel (to reduce cost) and when extreme heat, pressure, and RPMs come into play, lesser alloys can deform, corrode, or wear out early.
KMP invests in where it matters most – the metallurgy.
Why choose Inconel and not the cheaper alternative offered by others?
- Extreme Heat Resistance
Withstands temps over 1800°F (980°C) without deforming – ideal for turbocharged or high-compression engines.
- Corrosion & Oxidation Protection
Stays stable even after repeated exposure to combustion gases and thermal cycling.
- Superior Strength-to-Weight
Maintains high tensile strength without adding weight – reducing valve float and stress at high RPMs.
- Longer Lifespan, Lower Cost Over Time
Less wear, fewer replacements, and longer service intervals = better ROI.
- Proven in Motorsport & Aerospace
Trusted in Formula 1, endurance racing, and aviation – because lives depend on performance.
So, what happens when competitors cut corners?
Many lower-cost valves use materials that don’t match the original OEM specifications. These inferior metals:
- Soften at high temperatures, leading to valve seat erosion, deformation, and premature failure
- Struggle under high-RPM stress, increasing the risk of valve float and power loss
- Corrode faster, especially under aggressive thermal cycling — leading to inconsistent performance and more frequent replacements
- Reduce engine life, causing more downtime, rebuilds, and long-term costs
