MSD Distributor Cap
The vehicle's distributor cap is used in the automobile engine to cover the distributor and the internal rotor. The vehicle's rotor switches a high sparking voltage to the spark plugs so that these fire in the correct sequence. The distributor caps of your vehicle system are a prime example of a component that will eventually give in to heat and vibrations. And even if its bakelite housing has not broken or cracked, the carbon deposits and the eroded metal terminals can cause the distributor cap to fail. Though this may happen in many occasions, the part is an inexpensive part to replace. And if you are in the market for that replacement part for your stock and worn distributor cap, the MSD brand has the right distributor caps you have been looking for. All MSD distributor cap are extra and heavy duty, that are designed with the performance in mind and are molded from high quality, voltage insulating material and the use of low resistance terminals. Every distributor cap has one post for each cylinder and in points ignition systems there is a central post for the coil voltage coming into the distributor. In high energy ignition systems, where there are no central posts, the ignition coil sits on top of the distributor. And 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, in order to send the secondary voltage to the proper spark plug at the right time.
