SIERRA Ignition Conversion Kits 18-5285 Electronic Ignition Conversion Kit Fits 4-Cylinder Delco

Sierra High-Performance Electronic Ignition Conversion Kits provide the highest voltage for the hottest spark.

For 50 years Sierra has been producing parts engineered to meet or exceed the specifications of marine engine manufacturers and has gained the confidence of engine manufacturers and boat builders to a point of supplying them with OEM parts. Boaters and technicians can be assured a Sierra part will fit right the first time and restore function to OEM specifications.

Key Features

• Senses the current level in the coil and adjust the dwell to maintain peak energy throughout the entire RPM range
• Peak current level is reached just prior to spark, so ignition energy is sustained with less heat buildup, which increases the lifespan of the coil and ignition module
• Compared to the non-high performance kits, these develop, on average, three times more available energy between 3000 & 5000 RPM, and nearly double the available plug voltage
• Approved for use in all 50 states and Canada
