The ignition coil is a crucial part of your ignition system. It's function is to convert the 12 volt power of your vehicle's electrical system in to 35,000 or more volts. This produces a high intensity spark at the spark plug which then ignites the fuel in the cylinder. Coils in general will wear out over time and cause a misfire condition. In engines like this that use a coil, if the coil goes bad, the complete assembly needs to be replaced.

Perfect fit for 2011 Silverado 5.3
These were a perfect replacement for the stock coil packs. Super easy swap out. I’ve had them on for about 2000 miles so far and have not had any problems. Great price too!!
