      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.

            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.

            Too short to use on angle plug hole; unable to keep socket on tool to complete chase. Fine for straight plug holes.

                No it will not work. Pep boys sells a tap that will work and allow you to put helicoil in if that is repair you are doing.

                Not sure. I just gave it a shot on my town and country and it worked out well. I'm sure it is the same material, it is all about if the size is right.

                Looks like the SP515 plugs are 16mm thread. This chaser only does 14 or 18mm, so you need to get a 16mm chaser or a heli coil kit.

                it will assist in retreading the spark plug threads however if the spark plug has "popped out" of the cylinder head you will have to retap a larger hole and use a recommended new plug insert that once in place becomes a permanent part of the head. Look up Ford Triton Spark Plug Insert for more information. Good luck.
