Standard Ignition Distributor Rotor P/N:JR-79
Help route high-voltage spark to each cylinder in turn with the Standard Distributor Rotor JR-111. It is a direct-fit replacement for the listed application, the 1991 Honda Prelude. See the "Vehicles it fits" section for engine-specific details. The rotor turns with the distributor shaft and passes current from the cap's center terminal to each outer terminal, sending spark to the plugs in firing order.
A worn, burned or carbon-tracked rotor tip may show up as misfires, hard starting, rough running or hesitation. These symptoms can have other causes, so diagnose the ignition system before replacing parts. If the rotor is the cause, JR-111 replaces it. Inspect the distributor cap at the same time.
