This precision tool accurately replaces stripped Ford spark plug threads with new thread inserts. Works on the car without removing the engine head. This set includes a drill, tap, swedge tool, insert tool, 10 steel inserts, plus a vacuum adapter to remove shavings from the chamber. The tool set installs a new spark plug thread insert in the exact original position in approximately 20 minutes. IMPORTANT: An inspection scope must be used to insure all shavings are removed from the combustion chamber. An inspection scope is not included in the 65900 set. Order a 66090 scope and 66100 45º mirror attachment if needed. LIS65900
