The black nitride coating is a hardening treatment that even though it is not widely used as the chrome coating, it has several benefits and is becoming very popular, mainly for European and Japanese 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. Value 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).

Very good product, best sale
They let the cold air in, and the hot air out. My cams love them!
Great valves! Pretty much all there is to say. Have them in my built 1g and Evo! Never given me a problem.
The black nitride is a good touch. These valves are going to be put under a lot of stress and i picked these to go along with their supertech valve guides and valve seals for smooth operation. I trust that they will do their job as intended.
