The Pontiac ignition system is made up of a number of high-performing parts and components, and these ignition parts are crafted to withstand the pressure and heat that the system is well-known for. Its purpose is to create the right spark that will ignite the air and fuel mixture in the cylinder of the engine. The system will have to do this at the right instant and if the timing is off the mark, the engine will run poorly or may not even run at all. Specifically, for the ignition system to properly supply the right spark, it will need the cooperation of all the ignition parts and components. One of these ignition parts is the Pontiac distributor cap. From the name itself, ordinary drivers and vehicle owners will have the idea that this part is a device used to cover and protect another component. Though this understanding is half-true, it should be noted that the operation of the Pontiac distributor cap transcends that of being just a mere cover. Rather, this ignition component also has a say when it comes to the sending of the right amount of voltage to the right spark plug at the right moment. This component will typically have one post for each cylinder and in points ignition system, there will be a central post for the coil voltage coming into the distributor. On the inside of the cap, there is a terminal that corresponds to each post and the plug terminals are arranged around the circumference of the cap according to the firing order. From this, you will note that the Pontiac distributor cap is one indispensable part of the ignition system. So, equip your Pontiac with nothing but the best performance parts.
