Ignition Box, MSD SCI, Analog CD, Sport Compact, Silver, Each
At higher rpm, stock inductive ignitions cannot produce full power sparks, resulting in a loss of power or misfires. That's where the MSD SCI and SCI-L ignitions come in. They feature CD circuits that deliver powerful sparks at over 10,000 rpm. They're always at full power! Below 3,000 rpm, the SCI ignitions produce a series of sparks that last for 20 degrees of crankshaft rotation. That gives you smooth idle, quick starts, and even faster throttle response. The SCI-L ignitions have the same features as the SCI ignitions, plus the added bonus of an adjustable rev limiter.
