Car spark plugs are integral to the efficient operation of the engine, contributing significantly to the vehicle's overall performance and fuel economy. These plugs are designed to withstand high temperatures and pressures within the combustion chamber, providing reliable ignition and combustion. Properly functioning car spark plugs are essential for maintaining smooth engine operation, fuel efficiency, and emissions control, making them a critical component in the overall reliability and longevity of the vehicle.

ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.

The last step involves the actual pressing-in of the seal. There are tools and tool kits available that can help with seal installation. Their biggest benefit is that they apply a very uniform force to the seal case, eliminating the possibility of the seal seating in any way other than flush.

Oil Seals Enable Your Equipment to Operate Efficiently
Temperature - Just like pressure, the temperature that your oil seal will be operating in must be known so that you can choose one that can withstand the heat or cold. PTFE have the widest range of temperature, making them useful for machines who can see usage in extreme weather or elements.
Finding oil spots under a parked vehicle can be both worrying and stressful for any vehicle owner. If the seal’s leak is small, oil may start to accumulate on the underside of the engine. But as the leak gets bigger, the oil leak will become visible in the front side of the engine.
When installing a 38x52x7 oil seal, it is important to ensure that the seal is properly lubricated and aligned with the shaft. This will help to minimize friction and wear, and extend the life of the seal. It is also important to regularly inspect the seal for any signs of damage or wear, and replace it if necessary to prevent oil leakage.

Some aspects to consider when selecting this component are:
0.1 to 0.32 μmRa and 0.8 to 2.5 μmRz
and the lead angle to no greater than 0.05°. (There is a risk that the lead marks will impede the sealing performance of the oil seal: see Figure 5.)
Furthermore, iridium spark plugs are designed to withstand high temperatures and extreme conditions inside the engine. This means they are less prone to fouling and misfiring, even under intense driving conditions. This reliability makes iridium spark plugs a great choice for performance cars or vehicles that are used for towing or heavy-duty applications.
