Genuine Mercedes-Benz Spark Plug Coil Boot Grease (1.2 Oz) - OEM A0029890808

This is the real stuff—genuine Mercedes-Benz grease, specially formulated for spark plug coil boots and adapters.

It comes in a 1.2 ounce tube and is made in Germany.

Using this on the rubber boots helps them slide on and off easily, prevents them from sticking to the spark plug, and keeps moisture out.

It's a small but super important step during a tune-up to ensure a solid connection and protect those expensive coils.

If you're doing plugs on your Mercedes, grab this OEM tube (part #A0029890808) and do the job right the first time.
