    These MSD Digital SCI Plus ignitions deliver high output Capacitive Discharge (CD) sparks for complete fuel mixture combustion, especially at high rpm. They feature a retard stage to handle nitrous, making sure you don't get detonation from increased cylinder pressure, and a rev limiter that assists with firm launches. The 15 MHz micro-controller is the fastest of all digital ignitions, and gives you a smooth rev limit and precision timing. Easy-to-use rotary dials make adjusting the launch limit and retard amount simple and easy. MSD designed them to install easily on most 4, 6, or 8-cylinder engines with a distributor.
