Specs At A Glance

Good To Know

Q: What symptoms point to a bad ignition coil? A: A misfire, rough idle, hard starting, or a no-start with no spark at the plug can indicate a failed coil. Swapping the suspect coil and checking for spark is a common way to confirm the fault.

Q: Can I replace just one coil? A: Yes, coils can be replaced individually, though inspecting the plug, cap, and wiring at the same time is wise. On multi-cylinder engines, match the replacement to the original part number for correct operation.

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