LOCK-N-STITCH Inc. (LNS) has received approval from Ford Motor Co. for their hard anodized aluminum spark plug thread repair insert kit for Triton engines. The insert kits are marketed under their Full-Torque thread repair insert product line. LNS worked for more than three years with Ford engineers to develop and test the three types of tooling required to install the inserts to the proper depth.

The product is available to Ford dealers through Ford Rotunda. The same tools are available to engine rebuilding and machine shop customers in one master kit or in individual kits. The objective was to develop a permanent repair insert that could produce maximum heat transfer from the park plug to prevent pre-ignition with maximum thread strength that would not strip or come out.

A difficult hurdle that LNS had to overcome was to develop a simple way to easily and positively identify which type each head is. They cannot be defined by casting number, year or engine size. The solution is a probe that LNS designed and manufactures that works by simply pushing it down into the plug well, pulling it out and reading the chart engraved on the tool. The Ford service bulletin TSB 07-15-2 can be viewed at www.fulltorque.com/sparkpluginserts.htm along with the full step-by-step installation instructions with color photos.

You can contact LNS at (800) 736-8261 in the U.S. and Canada. Kits are also available through Goodson.
