51457 Fully Threaded Taper Seat

Question: Will my fully threaded spark plugs (all the way up to the taper) work with the inserts that come in the kit which have threads only about 1/2 way?

Answer: Yes they will. If preferred, we also have fully threaded inserts (PN 51457) which have twice the number of threads for more holding power. *Note that partially threaded plugs will NOT install properly in the 51457 fully threaded insert so the inserts included in the kit have to be used. These inserts are still much stronger than the original aluminum threads.

USA Made!

Needed a spark plug thread repair kit when my 2002 Ford F150 blew a spark plug. Why does Ford have an engine that blows sparkplugs? Anyway, Time Sert seemed to be the best fix. Doing a quick search online, the Internet confirmed this. I like that the Time Sert 5553 has free fast shipping from DenLors (unlike Amazon or Ebay) and that I could pick up a phone and actually talk to a real person! And most of all that it's made well and made in the USA!
