  • Stainless Steel
  • Retains High Temperatures
  • Designed for Turbo and Supercharged Applications
  • The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (microhardness is 800HV minimum)
  • Surface finish is smoother than with chromed stems, having less friction between stem and guide.
  • Valve seat surface is harder with the nitrided layer, lasting longer with lead free fuels, alcohols, nitro or other "explosive" mixes. Matches any kind of seats (nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper seats).
  • Higher rpm's engines take full advantage of all previous features. The higher the engine speed the bigger the power loss due to internal engine friction! The black nitride layer reduces this power loss due to less valve-guide friction.
  • The nitrided layer is adhered to the base material at a microscopic level, so does not"flake" or brake when the valves bend due to impacts with the pistons.
  • The Black Nitride applies to the whole valve while the chrome coating is only applied to the stem.

    Valve Specs:

    • Head Diam: 30.00mm (+1.0)
    • Stem Diam: 5.97mm
    • Length: 99.10mm
    • Part Number: TEVN-1016
    • Material: Black Nitrided
