How to Remove a Stripped Spark Plug

This article will teach you how to remove a stripped spark plug from your engine.

Spark plugs are necessary for an engine to create sparks and crank the engine, but they need to be replaced at intervals.

Although they might look rigid, they’re susceptible to breaking, striping off, getting stuck, and even melting when they’re often subjected to excess engine heat.

Removing a stripped spark plug from the engine isn’t as easy as you visualize it but with patience, it’s doable.

Unlike normal spark plugs that can be removed with a socket wrench, a stripped spark plug can only be removed successfully using a special nut extractor socket and a penetrant spray.

This nut extractor socket is built to embody the whole stripped spark plug while you get rid of it, it’s also the perfect tool since spark plugs are often situated in strategic areas.

Let’s see a step-by-step solution to remove a stripped spark plug from your car’s engine without wasting much time.
