MSD 6300CR SCI Sport Compact Ignition Control Cosmetic Repack

The MSD 6300CR is a Sport Compact Ignition (SCI) capacitive discharge ignition control — a cosmetically repacked version of the standard MSD 6300. Cosmetic repack units are fully functional and electrically identical to standard production units; they may exhibit minor cosmetic blemishes, scratched housings, or non-retail packaging, but carry the same proven MSD performance.

The MSD 6300 SCI is engineered specifically for sport compact vehicles equipped with a distributor-based ignition system. It delivers a high-energy capacitive discharge spark with up to 470 volts to the primary side of the coil and 110 millijoules of spark energy per firing — ensuring every spark fires at full power across the RPM range. This unit is OBD II legal and is designed to work with standard distributor-equipped sport compact engines.

Key Features:

• Capacitive discharge (CD) ignition design for full-power spark at every firing
• Up to 470 primary volts and 110 mJ of spark energy per spark
• Designed for sport compact applications with distributor-based ignition systems
• OBD II legal for street use
• Cosmetic repack — functionally equivalent to standard MSD 6300; may have minor cosmetic imperfections
• Will not work on vehicles with coil packs (distributor required)

This is a no-longer-available (NLA) closeout unit. The MSD 6300CR offers an opportunity to obtain proven MSD SCI ignition performance at a value price. MSD part number cross-reference: 6300.
