NGK 58957 direct ignition coil boot for the 2009-2014 Mercedes-Benz G550 V8 5.5L and other vehicles links each ignition coil to its spark plug. It is built to OEM tolerances, with original equipment fit and design.
A cracked or burned boot, a misfire or a rough idle can mean a coil boot has worn out. These signs alone do not prove the boot is at fault, since a worn spark plug can cause the same misfire.
The list also covers the 2010-2013 Mercedes-Benz S400 V6 3.5L and the 2007-2012 Mercedes-Benz GL450 V8 4.7L, along with many other Dodge, Freightliner and Mercedes-Benz models. Each engine takes one boot per cylinder: six on the V6 engines and eight on the V8 engines. Driving something else? Look up your year, model and engine in the "Vehicles it fits" section.
