Introduction
Spark Plugs: Have you been inspecting and replacing them?

The sparks plugs mounted in the engine's combustion chamber play a critical role by igniting the fuel-air mix.
Gasoline engines obtain power by compressing a fuel-air mixture of air and gasoline, then exploding this mixture by ignition. Spark plugs serve to ignite this fuel-air mixture. With the battery as the power source, the spark plug converts the electrical energy that comes through the ignition coil and distributor into a spark which ignites the fuel air mixture. In other words, without the spark plug, the engine doesn't run; the spark plug is a important part because its performance influences the overall performance of the engine.
Spark plugs are the heart of your engine!
