PERFORMANCE TOOL 14MM/18MM SPARK PLUG THREAD HOLE CHASER

When you're working on your engine and find that the spark plug threads in the cylinder head are a bit rough or damaged, the Performance Tool W80539 spark plug thread hole chaser is what you need. This tool is designed to clean out debris and gently re-form damaged threads, making it easier to properly seat your new spark plugs. It covers both common 14mm and 18mm spark plug sizes, so it's a versatile addition to your toolbox.

Using this chaser is straightforward. You simply thread it into the spark plug hole just like a spark plug, but it's designed to cut away any burrs or imperfections without removing excessive metal. This helps ensure a good seal for your spark plugs, preventing compression leaks and misfires. It's a well-built tool that can save you a lot of hassle compared to trying to clean threads with a pick or a tap that might remove too much material.
