Good To Know

Q: Should I apply thermal grease during install? A: Yes, applying a thin layer of heat-sink compound to the back of the module is critical to prevent overheating. A: Failing to use grease often results in premature module failure.

Q: Is this module the cause of no spark? A: A failed ignition module is a common cause for a no-spark condition. A: Always check your power supply and ground wires before assuming the module is the issue.

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