Detailed Description

This distributor rotor is a direct replacement component for Porsche 911 ignition systems, including 1984 and 1986-1993 models. The brass contact helps carry ignition energy through the distributor, while the phenolic rotor body is selected for electrical insulation and heat resistance inside the distributor cap.

This part cross-references EXEDY OEM 04163 for the same application.

Common Issues It May Address

• Engine misfire caused by worn rotor contacts
• Hard starting related to weak distributor spark transfer

Installation Notes and Tips

Verify distributor cap and rotor orientation before installation. The push-on mount should seat securely on the distributor shaft without forcing the part. Inspect the cap, terminals, and ignition wires at the same time to avoid repeat service. Confirm vehicle application by year before ordering, especially on Porsche 911 models with distributor service history.
