Mopar 56028394AD ignition coil for the 2005 Dodge Ram 1500 V8 5.7L and other vehicles steps battery voltage up to the high voltage a spark plug needs to fire. This Mopar ignition coil is sold individually.
A misfire, rough idle, hard starting or a lit check engine light can be linked to a failing coil. A fouled spark plug can also misfire, so these signs alone do not prove the coil is at fault.
It is also a Jeep Grand Cherokee ignition coil for the 2005 model with the V8 5.7L, and it fits the 2005 Dodge Ram 2500 V8 5.7L. A V8 5.7L has eight cylinders and takes eight coils, one per cylinder, so this listing is one coil rather than a coil pack for the 2005 Dodge Ram 1500 V8 5.7L. If your car is not named here, look up its year and engine in the "Vehicles it fits" section.
