Supertech Performance BMIVN-1045S BMW S54 Intake valve

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.

Specs:

  • Head Diameter - 35.00mm (+1.0)
  • Length - 117.50mm
  • Material - Black Nitrated
  • Stem Diameter - 5.97mm


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.

Good looks but cheap fabric
Size: Large, Color: Light Blue
The sizing is about right, but the fabric is really cheap, flimsy and rough. Disappointed and this is going back

Nice!
Size: Medium, Color: Bright Blue
My husband loves these. He’s got black, navy, bright blue, burgundy, grey…. and I’m sure I may be missing some! They hold up nicely after repeated washings in cold water in the machine and I always hang to dry. For golf they are fabulous because they are non constricting and comfortable while playing in the hot Florida sun which he does on a daily basis. They run very true to size….he takes his usual medium and they fit perfectly. Highly recommend!

I am thoroughly impressed with this Amazon Essentials white shirt. For the price, the quality is outstanding. The fabric feels soft, breathable, and has a good weight to it
