Here I am sharing my knowledge about spark plugs and their testing procedure.
Your spark plugs are what supply the spark that ignites the air/fuel mixture, creating the explosion which makes your engine produce power. These small but simple plugs create an arc of electricity across two leads that are not touching, but close enough together that electricity can jump the gap between them. Your spark plugs, along with the electrical and timing equipment which powers them, are part of what’s known as your ignition system.
When Do I Need to Change My Spark Plugs?
Most manufacturers these days will install “extended-life” spark plugs at the factory. They’re only marginally more expensive than a standard plug, and it sounds really good to the consumer. Extended-life spark plugs are usually rated for a lifespan of around 100,000 miles. As these plugs approach the end of their life, the gap between the two leads begins to widen, which leads to reduced efficiency and the possibility of misfiring. If your plug corrodes to the point where it breaks, it could do serious damage to the interior of your engine cylinder, which leads to an extremely expensive repair to get it fixed.
