- Dynamic seals called bearing isolators are used to shield bearings from external impurities. They are revolving (rotor) and stationary (stator) elements. O-rings or strong seals are used in some bearing isolators, while they are constructed like labyrinths in others.
Iridium spark plugs are becoming increasingly popular among car owners due to their superior performance and longevity compared to traditional copper spark plugs. These advanced spark plugs are made with a small center electrode made of iridium, a rare metal known for its strength and high melting point. This allows the spark plug to create a more consistent and powerful spark, resulting in better ignition of the air-fuel mixture in the engine.
