Yep, you are swapping in a better coil. This better coil creates a bigger spark, so you need to upgrade the plug wires. The new distributor cap is larger, and keeps the spark contacts farther apart, so that it doesn't jump into more than one one plug at a time.
the new coil, cap, and wires all hook up to the old stock distributor.
Take a look at this dist cap, it's alot larger than the tiny stock one
