      Cross threaded a spark plug at a location that would require engine removal for re threading the cylinder head and the thread chaser saved me.

      Cons

        Best Uses

          Comments about AutoCraft 14mm x 18mm Spark Plug Hole Thread Chaser:

          very easy to use. borrowed the Powerguard 02 sensor kit and purchased this because my sensor was very hard to remove from my 2003 Focus ZX3 2.0L. it was also the cheapest around compared to A*zone and P*boyz. the length of having the other thread helped in my situation with the sensor tucked under the header. use liberal amounts of rust remover spray for cutting oil - I used KnockerLoose. I will definitely do this with every 02 install.

            Comments about AutoCraft 14mm x 18mm Spark Plug Hole Thread Chaser:

            Old spark plug on 1 cylinder was very difficult to remove. New Spark plug would not even begin to thread into the hole. Ran this tool through about 5 times, slowly, going further each time. It cleaned the treads up, removing some material. Spark plug now threads in perfect.
