An aftermarket system allows for the replacement of the original equipment manufacturer’s (OEM) Opti-Spark ignition system found on specific General Motors engines. These engines, typically found in vehicles produced during the mid-1990s, utilized a unique distributor design that has proven to be a common source of performance issues and failures. This system commonly includes a new distributor, ignition module, and associated wiring. These aftermarket parts work together to improve upon the original design of the faulty system in certain vehicles.
The implementation of such a revised system can offer several advantages, including improved ignition reliability, enhanced engine performance, and simplified maintenance. The original systems were known for their vulnerability to moisture and heat, leading to misfires and reduced engine output. Modern alternative designs often incorporate more robust components and relocated distributors, mitigating these weaknesses. Furthermore, eliminating the factory system may simplify future diagnostic procedures and reduce the likelihood of recurring problems.
