The OTC Ford Spark Plug Removal Kit, No. 6918, helps eliminate plug breakage upon removal, speeding up the process of removing and replacing plugs for notoriously difficult-to-remove Ford three-valve engines that features a two-piece spark plug design. It locks the plug porcelain core to the protruding hex head and uses a collet assembly to lock onto the top of the plug, allowing the plug to be removed as one complete unit. If the plug has already broken off, an optional adapter can still pull the majority of broken plugs quickly and easily, via the plug hex. Applications include Ford’s 4.6L 3V, 5.4L 3V and 6.8L 3V engines found in the Mustang, F-Series, Expedition, Explorer and Lincoln Navigator.
