Refresh LT1 Opti-Spark ignition service with a Gen. 2 cap and rotor kit built for the correct 1990s LT-based distributor layout.

Opti-Spark Generation
Gen. 2 fitment matters because early and late Opti-Spark cap and rotor layouts are not interchangeable.

LT-Based Ignition Service
The cap and rotor help refresh the distributor-side spark routing on compatible LT1/LT4 applications.

Installation Notes
Confirm Opti-Spark generation, model year, and distributor style before installation.
