Pontiac was named after a native chief. Because of its high-performing parts and ever-popular vehicles, it has been prosperous for over half a century. During the development of Pontiac, many popular parts were built. One of them is the spark plug. A spark plug is essential for the engine to run. It must have the proper mix of fuel, compression, and a spark. The spark plugs come in many sizes ranging from 10 mm to 18mm.
Pontiac is famous for lots of high-quality parts. However, the old Pontiac spark plug parts might lead to poor functions and an unpleasant driving experience after years of usage. Here are the steps to service the spark plugs. You should disconnect the negative battery terminal. Remove the spark plug wire boots by pulling and twisting them. Remove the parts using the correct size socket. Then, adjust the new spark plug gap with the spark plug gap tool and add anti-seize to the threads. Next, tighten the new parts to proper torque. Then, plug in the spark plug wire boot to the new set of plugs. Spark plugs have different heat ranges. The longer the spark plug insulator, the hotter it will operate, and the shorter the insulator, the cooler it will operate. There are much better and smarter parts and devices.
