Specs At A Glance

Good To Know

Q: Why do I need a camshaft sensor plug? A: When swapping to a front camshaft sensor layout, the original rear sensor port is left open. This plug seals that port to prevent engine oil from leaking out.

Q: Do I need to apply sealant or RTV when installing this plug? A: No, the dual rubber O-rings provide a secure seal, though a light coat of engine oil is recommended on the O-rings before pressing it in.

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