Supertech Performance BMIVN-1030 BMW S42 / M42 / M50 / S50 / M52 / S52 / M54 Intake valves

Set of 12

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.

Not a strong toy for chewers.
Color: Yellow
Not quite as strong as its description. My dog chewed off its foot within the first 10 minutes . I expected it to be stronger because it’s made of Kevlar material but it’s not that durable. Save your money it is far from being durable / indestructible.

Leave a toy for the dog when going to work, and no housebreaking when coming back
Color: Purple-Blue, Size: 2pcs
The dog is quite clingy. Every time it sees me put on my shoes to go out, it gets nervous. Since having this bear around, when it goes out, its attention is all on the toys, and when it comes back home, its mood has become much more stable.

Keeps my dog busy and actually holds up
This jigsaw-style dog toy has been a game changer for keeping my dog entertained. The design is super versatile—you can spread peanut butter (or yogurt, wet food, etc.) into the grooves, and it keeps them busy licking for a long time. What I like most is that it’s not just a lick mat—it’s also a durable chew toy. The material feels strong and holds up really well, even with a dog that usually destroys toys pretty quickly. Toys made from rubber or similar materials tend to last longer and are safer for chewing compared to softer options. The grooves and compartments make it a little more challenging (in a good way), so it takes my dog longer to get through the treats. I’ve even tried freezing peanut butter inside, and that keeps them occupied even longer. Lick-style toys like this are great for slowing dogs down and keeping them calm and engaged. It’s also been really helpful during times when I need a distraction—like when I’m busy, cleaning, or even during grooming. Pros: • Durable and holds up to chewing • Can use peanut butter, yogurt, or other soft treats • Keeps dogs busy for a long time • Helps with boredom and anxiety • Freezable for longer use Cons: • Can get messy depending on what you put in it
