Ignition Tune-Up Kits

Electronic Ignition Conversion Kit, Fits 8-Cylinder Prestolite with Clip Cap from SIERRA
They sense 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.
