Good To Know

Q: How often should this O-ring be replaced? A: It is best replaced each time the oil filter cover is removed, since the old ring can harden and lose its seal. Inspect it during every oil service for cracks or flattening.

Q: Does this O-ring arrive pre-lubricated? A: No, it should be lightly coated with clean engine oil before installation to help it seat. That also reduces the risk of pinching during cover refit.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
