If you're experiencing rough idle, poor acceleration or mediocre fuel mileage, integrating new spark plugs might be the solution to this issue. Spark plugs have two primary objectives. The first being to ignite where electrical energy is moved through it, crossing the gaps in the plugs firing end if there is ample voltage provided to the plug. This spark efficiently ignites the gasoline and air mixture in the combustion chamber. The second is to remove heat from the combustion chamber where the spark plug functions as a heat exchanger that pulls unnecessary thermal energy from the combustion chamber and moves heat to the engine's cooling system. The temperature level of the plug's firing end is appropriately maintained to prevent pre-ignition as well as fouling.
