The RTW (Round-The-World) Spark Plug Holder comes complete with a cold-forged, 304 stainless steel multi-tool which allows you to swap out your spark plugs without having any other tools on hand. The RTW Spark Plug Holder will fit on any motorcycle with a USA-sized motorcycle license plate. The slotted, investment-cast aluminum spark plug holder will mount at the top or bottom of any license plate, or on the backside of your license plate bracket as long as there is room. Simply unbolt your license plate, bolt the RTW Spark Plug Holder in place and thread in a spare pair of spark plugs. The wrench multi-tool includes a spark plug gapper, an inch and metric ruler, bottle opener, straight screwdriver blade and 1/4" hex driver. Spark plugs not included!
