Detailed Product Overview

The JR-79 is a distributor rotor for ignition systems that require a push-on style rotor with brass contacts. In service, the rotor routes high-voltage ignition energy through the distributor cap to the proper plug wire terminal, helping maintain stable ignition timing and cylinder firing. This part number is used across select Nissan 200SX, 210, 310, 510, 720, 810, Pulsar NX, and Honda Accord and Civic applications, making it a direct-match service part for specific emissions configurations and model years.

For buyers searching for a Nissan 200SX distributor rotor, Honda Civic distributor rotor, or Standard Ignition JR-79, this part matches the listed applications by year, model, and emissions setup.

Common Problems This Part Can Address

• Engine misfire caused by worn rotor contact surfaces
• Hard starting related to weak spark transfer inside the distributor
• Intermittent ignition performance from a damaged or carbon-tracked rotor
• Rough idle tied to inconsistent spark routing
• Ignition service needs on listed Nissan and Honda distributor systems

Installation Notes and Tips

Verify distributor style, emissions configuration, and model year before installation. The push-on mount should seat fully on the distributor shaft, and the rotor contact should align correctly with the cap terminals. Inspect the distributor cap, ignition wires, and related ignition components during service to confirm the repair addresses the full ignition path.
