Specs At A Glance

Good To Know

Q: How do I know if my ignition coil needs replacing? A: Common signs include hard starting, misfires, rough idle, or a loss of top-end power. Testing primary and secondary resistance against factory specs confirms whether the coil is failing.

Q: Can I install this coil myself? A: Yes, it mounts with factory-style connectors and hardware, so basic hand tools are typically enough. Disconnect the battery before starting and route plug wires exactly as removed.

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