Sierra 18-5294 Electronic Conversion Kit for 6 Cylinder Delco Distributors

The Sierra 18-5294 Electronic Conversion Kit converts a 6 cylinder Delco distributor from breaker points and a condenser to true solid-state electronic ignition. Removing the points and condenser eliminates the wear-prone contact surfaces that cause misfires and require periodic gap adjustment, replacing them with an electronic trigger that fires consistently across the RPM range. The kit is designed as a one-piece unit with a simple two-wire hookup, so it installs into the existing distributor housing without modifying the ignition system beyond the points and condenser it replaces. It continues to use a standard coil, cap, and rotor, meaning the rest of the ignition system stays as-is.

Timing precision is held to within 1/4 degree across a 0 to 6000 RPM range, giving a stable spark advance curve from idle through high RPM. The kit is also built to work alongside Sierra's Flame Thrower coils 18-5466 and 18-5469 for owners looking to pair the conversion with an upgraded coil. It is intended for 6 cylinder Delco distributor applications only; other Sierra conversion kits are sold separately for different distributor types and cylinder counts, so confirm the distributor style before ordering.
