I needed a forklift part and wasn’t sure which one fit. They asked for the model and serial number, got back to me quickly, and made sure I ordered the right one. Really helpful.

Frequently Asked Questions

Q: Will this coil pack fix a misfire and check engine light? A: Yes, if worn ignition coils are the cause, installing this set restores consistent spark delivery, eliminating misfires and associated trouble codes.

Q: Should I replace all six coils at once? A: Replacing all six coils ensures uniform performance and prevents a single aged coil from causing future misfires, which can damage the catalytic converter.
