The vast majority of Powersport vehicles require 5/8" (16mm) spark plug socket wrenches, including Harley-Davidsons, four-stroke dirt bikes, ATVs and snowmobiles; sport bikes plus many cruisers and touring bikes. Some vehicles require a thin-wall sockedt to fit into the head, negating the use of typical forged mechanics sockets. In addition, spark plugs may be situated rather deep into the head. To address these special needs, CruzTOOLS has introduced a range of 5/8" spark plug sockets at three lengths - four, five and six inches - to match any given vehicle requirement. Sockets include a rubber grommet to hold the plug in place, and meet ANSI tolerances. An 11/16" (17mm) wrench can be used to loosen or tighten the spark plug socket.
