Product Details
Features
- Gen. 1 Opti-Spark layout matches the correct LT-based distributor generation
- Cap and rotor service components help restore LT1/LT4 spark routing

- Useful during 1990s LT-based ignition maintenance and distributor service
Description
Bring cleaner spark routing back to an LT-based Opti-Spark distributor with a Gen. 1 cap and rotor service kit.
Opti-Spark Generation
Gen. 1 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.
