- Quality control is a crucial aspect of the spark plug factory, with rigorous testing procedures in place to ensure that each spark plug meets the required standards
spark plug factory. Spark plugs undergo testing for resistance, durability, thermal performance, and overall functionality before they are approved for use in vehicles.
If this is not possible, you may be able to fit the lower retaining bolt into the upper mounting support, to hold the engine level. Or the gearbox may have to be jacked up and supported.

Because of the higher temperature resistance of FKM, this material is also chosen for applications where higher speeds play a role, which raise the temperature at the sealing lip considerably. Usually, using FKM will result in a longer life than using NBR. This compensates the higher price of FKM compared to NBR, as an FKM does not have to be replaced as frequently. The low temperature resistance of standard FKM is limited to -15 ˚C.
