Good To Know

Q: What are the signs of a failing CDM module? A: Typical symptoms include dropping spark on a cylinder, engine misfires under load, or a complete lack of spark when hot. Testing with a spark gap tester can confirm weak output.

Q: Should all CDM modules be replaced at the same time? A: While not mandatory, replacing all modules together ensures uniform spark strength across all cylinders and prevents future ignition system issues.

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