Helicoil 5334-14 Save-A-Thread Thread Repair Kit M14 x 1.25

This kit is easy to use with the supplied parts. Worked great in less than a hour. If you have a spark plug thread problem this is the kit Hands down!!!

This product performed just as promised. It was well worth the investment and is re-usable. It saved me a lot of money in repairs to, or replacement of, an old lawn mower that was in excellent condition except for a stripped spark plug hole. I highly recommend this product.

After breaking off the spark plug on my motorcycle leaving only the threaded part I started researching how to fix it. After removing the head and drilling out the old threads I tried to re-tap the threads to no avail so it was on to a new thread insert. I wasn't thrilled with the idea of a "coil" fix was shocked when I found out the price for the coil kits so I was very excited when I found the Save-A-Thread kit with solid sleeve inserts. It worked like a charm. I had the hole expanded, re-threaded and the insert in place in less than 20 minutes. At half the price or less than the other "coil" kits I'd found the Save-A-Thread kit is a life saver.
