Supertech Performance BMEVI-1040S BMW M3 S54 Exhaust valve. This kit includes 12 valves.

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 - 30.50mm (STD)
  • Length - 119.10mm
  • Material - Inconel
  • Stem Diameter - 5.95mm
Note: To be used with KPR-6S/7


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.

The Best buy for my kitchen
Size: Large-3SET, Size: Large-3SET
Great quality cutting boards! The carbonized bamboo feels durable yet lightweight, and they look beautiful in the kitchen. I love that they come pre-oiled and are non-toxic. The three sizes are super practical, and the hanging hole is a nice bonus. Definitely a great buy!

High quality, eco-friendly, and beautiful!
Size: Large-3SET, Size: Large-3SET
I’m obsessed with this set! The carbonized finish looks stunning on my counter, and I love that they are non-toxic and eco-friendly. They came pre-oiled and ready to use, and the different sizes are perfect for everything from meal prep to serving charcuterie. The juice grooves are a total game-changer for keeping my counters clean. Definitely worth it for any busy kitchen!

Great quality bamboo cutting boards
Size: Large-3SET
These cutting boards are very well made and feel solid. The bamboo is smooth, nicely finished, and already pre-oiled, which is a big plus. I like having three different sizes — it makes food prep much easier depending on what I’m cutting. They look good on the counter, don’t slide around much during use, and clean easily with a quick wash. For the price, the quality is excellent. I would definitely recommend these if you’re looking for durable, eco-friendly cutting boards for everyday kitchen use.

Absolutely gorgeous cutting boards. Bamboo is a rich deep drown, sturdy with all sorts of foods - vegetables, meats, fruit etc. Nothing sticks and very easy to hand wash - makes food prep a breeze. Great value, size as described, easy storage upright for drying.
