- The effectiveness of a spark plug is measured by its heat range, referring to how quickly it can dissipate heat. A spark plug that's too cold may not allow proper fuel combustion, leading to engine issues. Conversely, a spark plug that's too hot can cause pre-ignition, damaging the engine. Therefore, selecting the right spark plug for a specific engine is crucial.
When selecting auto gaskets and head gaskets, it is essential to prioritize quality, durability, and compatibility with specific vehicle models. High-quality gaskets are designed to withstand the demanding conditions of automotive operation, providing reliable sealing solutions that contribute to the overall performance and safety of the vehicle. Choosing reputable suppliers and manufacturers known for producing high-quality auto gaskets and head gaskets is crucial to ensure the reliability and longevity of these critical components.

Oil seals are protective elements. They prevent the mixing of water and lubricants within a machine, thereby ensuring optimal machine functionality. Also, oil seals help to prevent lubricant leakage at high pressure like when the machine is working at an extremely high rate. Not only that, radial shaft seals stop foreign components from entering a machine. This is because they can contaminate the lubricant and even damage the machine.
