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.

It's decent
Scent: Santal Vanilla
First off, I am a man who has been searching high and low for a good "natural" deodorant. The smell (Santal Vanilla) is amazing and really wanted to like this deodorant more. However, it just does not last. I get about 6hrs out of this before it starts mixing with the body smells and by 12hrs I have to re-apply. And I am currently using it in the winter, not sure how it would last in the middle of a hot summer. Also, the stick is very hard and tacky. Like rubbing a blue racquetball on your pits. It literally pulls my hair out when applying. If you shave it might not be an issue. Anyway, I'll use up the rest of it but only for short occasions and won't be re-purchasing.

Smells good, but….
Scent: Citrus Blossom
Citrus smell is very nice but the deodorant properties do not last. For the price, this factor should not be an issue. Doesn’t seem a good value.

Pleasantly surprised.
Scent: Rose Vanilla
As with most deodorant, I was actually expecting a pretty potent smell with this. I'm very happy to report that's not the case. The scent is pleasant, but not overpowering. I just put a few swipes on before heading out or going to the gym, and I smell nice for the next few hours. Another nice thing about it, such as when going to the gym as I mentioned, is that it doesn't leave a bunch of nasty residue on my shirt or workout clothes. There's a little bit, sure. But not like some deodorants that leave a crap load of it. It's not that it's difficult to wash out. It's just that it's annoying. I don't really know how much I can say about a stick of deodorant. It smells nice, lasts a long time, and works great. Isn't that what it's all about, at the end of the day?

Excellent deodorant!
Scent: Santal Vanilla
This is great deodorant. I have used it for a month now and it prevents all underarm odor for the entire day. Its formula is smooth and easy to apply without being rough on my skin. Its scent is very natural and almost unnoticeable. Overall this is great deodorant that works well at hiding underarm odor. I love that it's organic and doesn't contain aluminum, too! This is a great product that I would get again. It's long lasting and feels good on my skin.

Not for everyone
Scent: Santal Vanilla
This product smells amazing but unfortunately did not help. By hour 5 of wearing this product, I had body odor. Not every body is the same, so it’s because it didn’t work for me doesn’t mean it won’t work for someone else.
