Is Grease Required When Installing Spark Plugs on Vehicle

Expert Reply:

Sounds like you are asking if you should install dielectric grease in any situations when swapping spark plugs. The answer is yes. Basically you want to put it in both sides of the spark plug wires. Where it connects to the coil and where it connects to the spark plug. Do NOT put any on the spark plug electrode though.

For grease we have # 11755.
