Dodge Spark Plugs

All vehicles powered by a gasoline engine need a set of spark plugs to run. These components are screwed into the cylinder head to generate a spark that ignites the air-fuel mixture in the combustion chamber. The number of plugs depends on the number of cylinders. Besides igniting fuel, they also help to cool the cylinders and transfer part of heat to the cooling system. If your Dodge lacks power during acceleration, if the engine misfires, or if the fuel mileage is inexplicably reduced, you should check and possibly replace the spark plugs.

The materials, design, and quality of these parts define their heat range and performance. The central electrode can be made of nickel, iridium, or platinum. The quality and design of its insulation influence the ability to remove heat from the combustion chamber. This ability is measured through the heat range. Based on this value, the plugs can be hot or cold, and each type fits different types of engines and has to meet various requirements. In our online store, we sell a wide selection of top-notch Dodge spark plugs designed and built to perfection by reputable aftermarket companies.
