If there is one thing on your vehicle that has the fire of life, it would be your EZGO NGK Spark Plug for 1991-Up 4-Cycle models. Bad jokes aside, the unit is directly connected to the ignition coil via the plug boot and wire. The ignition coil produces the high-level voltage needed to produce the spark. All the plug is doing is acting as a conduit for the electricity to pass through. Once that happens, all of the built-up energy gets burned off as a spark. This happens dozens of times every second and, over time, will wear down the spark plug until it is no longer capable of firing. This is why it is a good idea to have a few on the shelf.This golf cart spark plug is the exact one used in your golf cart from the factory. It does not get better than NGK; most brands use them as a default. Skip trying to cross the part numbers and get yours ordered from Buggies Unlimited today.
