Supertech Performance BMEVN-1030 BMW S42 / M42 / M50 / S50 / M52 / S52 / M54 Exhaust 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 - 30.50mm (STD)
  • Length - 105.65mm
  • Material - Black Nitrated
  • Stem Diameter - 5.96mm


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.

Gentle on Skin, Great Value
Color: 6pcs
Great quality and easy to use. These dermaplane razors remove peach fuzz and shape eyebrows with precision while being gentle on sensitive skin. My skin feels smoother, makeup applies better, and the 6-pack is a great value. Definitely a great purchase!

I really like these I would buy again
Color: 6pcs, Color: 6pcs
I’m honestly so impressed with these dermaplane razors! They came in a cute little storage bag, which I love because it keeps everything clean and organized instead of just tossing them in a drawer. The variety in sizes is also a huge plus—it makes it easy to use around different areas of your face, especially eyebrows and smaller spots where you need more precision. The blades feel gentle on the skin but still get the job done, removing peach fuzz and leaving my face feeling super smooth. I’ve used a few different brands before, and these are definitely a great value for the price. Perfect for at-home touch-ups without irritation.

Smooth Skin Made Easy! ✨
Color: 6pcs, Color: 6pcs
These dermaplane razors are a game-changer (per my wife) when it comes to at-home facial care. This pack of six razors works wonders on peach fuzz, eyebrow grooming, and exfoliating your face. The blades are sharp enough to get a clean, close shave but still gentle on the skin, making it great for beginners or anyone with sensitive skin. Plus, the ergonomic handle makes them easy to control, which helps with precision when shaping your brows. Compared to other dermaplane tools she's tried, these are definitely better quality and last longer before getting dull. Some cheaper ones she's used before start snagging or feel rough after just a couple of uses, but these stay sharp longer and glide smoothly across the skin. One minor downside is that the cap can be a little loose, so be careful when storing them to avoid accidental nicks. Overall, if you're looking for a convenient way to keep your face fuzz-free and smooth without salon prices, these razors are a great buy. You'll definitely notice the difference in your skin texture and makeup application after using them.
