How Do You Gap Iridium Spark Plugs?
Spark plugs are an essential component of a car’s operation. Like the name implies, spark plugs literally provide a spark that ignites the fuel in your car’s combustion chamber, moving the pistons up and down and giving the engine its power. While iridium spark plugs, which are the most common type, are relatively easy to remove and install, they must sometimes be properly gapped before installation, which means altering the distance between the ground electrode and the center electrode to provide a longer or shorter spark. This is a simple, yet delicate, task that requires concentration and care. Identify the center electrode and ground electrode. The ground electrode will be the copper-colored electrode curving over the top of the spark plug. The center electrode will be the silver-colored electrode sticking directly out the top of the spark plug and will end directly underneath the curvature of the ground electrode. You must take great care to never touch the center electrode or the
