Standard Ignition AL-166 Distributor Rotor

Distributor Rotor for Reliable Spark Transfer

The Standard Ignition AL-166 distributor rotor is built for consistent ignition performance in compatible Jeep applications. It uses a high-dielectric alkyd body to help resist dirt buildup and reduce carbon tracking, while solid brass segments support strong conductivity and voltage transfer to the spark plugs.

Compatible With 1970-1971 Jeep CJ5 ignition systems, this distributor rotor is a direct service part for restoring proper distributor function. The AL-166 is also referenced by DENSO Auto Parts 671-4153 and Hygrade Tuneup 1551 for the same application.
