They also feature a good electrode gap, which determines the distance between the center electrode and the spark plug's outer shell They also feature a good electrode gap, which determines the distance between the center electrode and the spark plug's outer shelltruck spark plugs. A smaller gap results in a higher voltage and thus a more effective spark, while a larger gap provides a longer life to the spark plug. The best seal performance is achieved when close shaft and bore tolerances are present. Other factors include shaft eccentricity, end play and vibration.
When selecting spark plug wires and new spark plugs, it is essential to prioritize quality, compatibility, and performance specifications. High-quality spark plug wires should be designed to withstand high voltage and heat, ensuring reliable transmission of electrical current to the spark plugs. New spark plugs should be selected based on the specific requirements of the vehicle, including heat range, electrode design, and material composition, to ensure optimal ignition and engine performance.

What are rotary shaft seals?
If the shaft or housing gets damaged, it must be repaired. If you replace only the oil seal, but the shaft or bore remain damaged, then there is a chance of premature failure or leakage. You can easily repair the shaft, for example using an SKF Speedi-Sleeve.
Other important factors are ensuring the hardness and roughness of the shaft are correct. A shaft hardness of HRC 45 is recommended for a rubber sealing lip, with a roughness of Ra 0.4-0.8. A higher shaft hardness of HRC 60 and shaft roughness of Ra 0.1-0.4 is recommended for a PTFE lip.
