Replacing the spark plug O-ring is a relatively simple task that can be done by a trained mechanic or DIY enthusiast. The new O-ring should be lubricated with a small amount of oil before installation to ensure a proper seal. It is also important to tighten the spark plug to the correct torque specifications to prevent any leaks or issues with the seal.Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.
