: the metal case supports the rotary shaft seal, ensuring the structural stability.
Car iridium spark plugs are a popular choice for modern vehicles due to their durability, high melting point, and superior conductivity. Iridium spark plugs offer enhanced performance and longevity compared to traditional copper or platinum plugs. The use of iridium in the electrode design allows for a smaller center electrode, promoting more efficient combustion and improved engine performance. Car iridium spark plugs are known for their ability to maintain optimal engine performance over an extended service life.
Friction modifiers: Friction modifiers help reduce friction when your engine is operating under high temperatures and with heavy loads. This additive can also help you maximize your fuel efficiency.
Oil seals close off the space between stationary and moving components in the mechanical equipment. It saves the lubricant from escaping through the equipment and ensures smooth operation of the machine.
