Performance
The MSD Digital 6-Plus Ignition Control combines terrific power, digital accuracy, and great accessories making it ideal for street/strip applications. Every spark of the Digital 6-Plus Ignition is packed with 135 millijoules of spark energy and 535 primary volts. When used with the MSD Blaster HVC Coil (121-8252), a spark with over 300 milliamps burns across the plug gap for 400 microseconds. Below 3,300 RPM the Digital 6-Plus produces a series of sparks that burn in the cylinder for up to 20° of crankshaft rotation. This incredible heat ensures combustion to produce great power, quick throttle response, smooth idle, and fast starts.
