NGK 58951 direct ignition coil boot for the 2003-2006 Kia Sorento V6 3.5L and other vehicles connects the ignition coil to the spark plug. It is built to OEM tolerances, with original equipment fit and design.
A cracked, hardened or burn-marked boot can mean it is worn out, and a misfire can show up as it fails. Misfires also come from the plug or the coil, so look the boot over with the engine off and cool before you replace anything. The fitment calls for three boots per vehicle.
The 2003-2006 Kia Sorento V6 3.5L, the 2003-2006 Hyundai Santa Fe V6 3.5L and the 2004-2006 Kia Amanti V6 3.5L all take this boot, as do other vehicles. If your car is not one of those, open the "Vehicles it fits" section and check your exact model and engine there.
