The 5553 thread repair kit is used for repairing failed spark plug threads over the fender. This kit was originally designed for the Ford Escort, that shows how long this kit has been around. Now the 5553 thread repair kit is primarily used on Ford 4.6 and 5.4 engines Triton and InTech DOHC's. The kit is also used on many other applications that use a tapered Metric 14 x 1.25 spark plug. The drill bit also called a reamer, is a step design that perfectly cuts a centered hole every-time even in hard to reach areas. Because of the unique stepped design there's no need for a line up adapter for multiple applications. The tap is also a stepped design that will guide straight in without and adapter like some competing brands require. 

Check to make sure the valves are closed without removing the valve cover with the optional 389-4000 Leak Tester.

*Note fully threaded spark plugs require a different insert in addition to this kit. The 51457 is the most popular fully threaded one which is 16.8mm long with a taper seat (requires 51484A to be used on setting tool). They are sold separately.

The Time Sert 5553 works on many Ford engines, since many use the M14x1.25 taper seat spark plug. Also because of the method that Time Sert uses to align the reamer, which is stepped tooling that works the same on any spark plug hole. It doesn't require a special line up adapter. It is the first choice for Triton engines which are 2 Valve. It also works on any M14x1.25mm spark plug hole. Here's a partial application list of Ford engines; 1.6, 1.9, 2.0, 2.3, 2.5, 2.8, 2.9, 3.0, 4.0, 4.2, 4.6, 5.4, 5.8 and 6.8 that have TAPERED seat M14x1.25 spark plugs.
