Do newer cars have spark plug wires?
A: Many newer vehicles do not have spark plug wires; they have “coil-on-plug” (COP) ignition systems. By eliminating the spark plug wires, your vehicle has a more reliable ignition system. The coil-on-plug system eliminates the need for high voltage spark plug wires that can cause ignition problems over time.
How is the distributor Connected to the spark plugs?
