Supertech Performance BMIVN-1030 BMW S42 / M42 / M50 / S50 / M52 / S52 / M54 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 - 33.00mm (STD)
  • Length - 106.1mm
  • 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.

Cushiony and lightweight sneakers!
Size: 5.5 Toddler, Color: Gold/Rainbow, Size: 5.5 Toddler, Color: Gold/Rainbow
The shoes are excellent quality! I was worried that the soles would be heavy since they are a little thicker than other toddler shoes, but this is not the case. The shoes are lightweight and run true to size. They were a little hard to put on the first two times and I thought, "Oh no, they must be too narrow." However, after my toddler wore these for a few hours each time, they stretched out and I checked her feet and did not notice any signs of discomfort, such as impressions on her feet from the shoes and/or redness. Toddler walked "normal" and even ran in these. The style is supercute (gotta love the subtle sparkles) and athletic and they appear to give her a lot of support. I can't speak to durability as she has only worn them for a few weeks but so far, they held up well and I have no issues with the velcro. I am glad they softened and stretched out after a short time of wear and they have plenty of cushion! Overall, these are great and no complaints here. I highly recommend!

Great looks for any outfit choice
Size: 12 Toddler, Color: Black/Grey
I was proud to see my first grader run their first mile on these shoes. The look and color is great for either a boy or a girl, and matches with either neutral colored or bright outfits. My kiddo found it easy to put on and adjust snuggly, so it’s nice having a shoe that doesn’t require an adult to calibrate and tighten just right (like my kids soccer cleats!). This is several steps past your cheap sneaker and I can tell it will comfortably get many more miles from my kid.

A good choice
Size: 4 Toddler, Color: Black/Grey
This is a great pair of shoes with excellent durability and color. It’s a classy little shoe that looks good and had a good fit. That was true to it sizing. It’s an excellent value for the money and they held up well throughout testing. No flaws were found in any of the materials and workmanship was phenomenal. If I could give it more than five stars I would.

Comfortable!
Size: 12.5 Big Kid, Color: Purple/Turq
My daughter loves these. She’s5. We got the size 12.5 and they fit her well.. a little space between her toes and the tip of the shoe but just the right amount. She says they are comfortable and good for her PE class and playing outside. We got the blue and then I ordered the black cause she loved them so much. They were on a great sale too!
