Supertech Performance BMEVN-1040 BMW M3 S54 Exhaust valve 30.5x5.95x126.10mm - SS/Black Nitrided/Stock size

Supertech valves are the best on the market, made from one piece of forged stainless steel for the ultimate in strength and durability. Supertech valves go through a special heat treatment process that obtains the right amount of harness for each engine to ensure the ultimate valve for your performance motor. Supertech offers their valves in either chrome coating, used in high performance valves, or hardened black nitrided which is most popular in European and Japanese motors.

Supertech High Performance Race Engine Valves features:

  • 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.

Inexpensive but certainly not 'cheap'
Color: Silver1
These work well and feel like very good quality far in excess of what you might expect for the price. I am very happy with my purchase.

great but one flaw
Color: 1pcs-Sliver-304
almost everything about this pepper grinder is perfect. the glass the turny bit and how easy it to use and clean is great. its such a simple and accessible piece of kitchen utility and its pretty in its simplicity too BUT! there is a little plastic ring that keeps popping out as i use it. the peppercorns will get stuck behind it and work it out every time i use it and it falls out into my food about every other time so i have to keep popping in and out that little plastic ring and clearing out the pepper and hoping i don't lose it or eat it.

Awesome product
The product is very good and holds a lot of pepper corns. It is also easy to open to add more corns. The price is very reasonable.
