Product Details

This Standard Ignition distributor rotor, part number JR-155, is made for ignition distributor service on 1993-1997 Nissan Altima models. The rotor transfers ignition energy through the distributor as the engine runs, and its phenolic construction helps maintain separation between the contact path and surrounding components. The aluminum contact material and bolt-on design support a straightforward replacement during distributor maintenance. This part cross-references CSF 3942 for the same application.

Common Issues It May Address

• Engine misfire caused by worn rotor contact surfaces
• Hard starting related to distributor ignition wear

Installation Notes

Verify distributor compatibility before installation and match the rotor to the existing mount style. Inspect the distributor cap, terminals, and related ignition components for wear before reassembly.
