A spark plugs reach is calculated by the length of the threads. It is measured from the seat of the plug to the end of the threads. It should be noted that the reach does not include the electrodes, or an extended metal shell. When custom-selecting a spark plug, the electrode length and projection should be included in the calculation when taking into consideration the clearance in the combustion chamber.
Our spark plug is located at the front of our engine underneath our spark plug wire. The first thing we need to do is wiggle that spark plug wire off of the spark plug. Then we are going to take a spark plug socket and slip that over the top of our spark plug and remove that spark plug from our engine.
