If you're driving a Dodge, Chrysler, Jeep, or RAM with that popular 3.6L engine, this ignition coil and spark plug set is exactly what you need for a tune-up. You get SIX ignition coils AND SIX spark plugs - everything required to refresh your ignition system all at once. These UF648 coils are compatible with a ton of vehicles including Avengers, Chargers, Journeys, Grand Cherokees, 300s, and many more from 2011-2016 model years. They're made with premium copper wire and high-insulation epoxy resin that stands up to heat and moisture, providing strong, reliable sparks for better combustion. The set comes with a solid 2-year or 60,000 km warranty too. When your ignition coils start failing, you might notice misfires, rough idling, or reduced fuel economy. Replacing them as a set (along with fresh spark plugs) ensures even performance across all cylinders. Installation is pretty straightforward if you're handy with basic tools, though the placement can be tight on some models. This complete set saves you the hassle of buying parts separately and ensures everything works together perfectly.
