This is a CDI ignition module for Ski Doo snowmobiles, engineered to manage spark timing and ignition output for reliable starting and consistent throttle response. It is an electrical replacement component designed for the MX Z 440 F, Z 583, Z 670, Safari Cheyenne, and 503 F/C 140 models from the 1990s.

It restores dependable performance in the MX Z 440 F, Z 583, Z 670, Safari Cheyenne, and 503 F/C 140, making it a direct functional substitute for the original component.

Good To Know

Q: Will this CDI work on a Ski Doo from a different year? A: Fit depends on the exact wiring and ignition curve, so confirm your model and serial number before purchase. The listed years (1997 and 1991) are the primary intended matches.

Q: What are signs the old CDI is failing? A: Common symptoms include no spark, intermittent misfires, or an engine that cranks but will not start. Replacing the CDI often restores normal ignition in these cases.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
