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: Do these ignition coils require any programming or relearn procedure? A: No programming is needed; the coils are plug-and-play replacements and work with the factory ECU calibration.
Q: Are the spark plugs pre-gapped? A: Yes, the spark plugs arrive pre-gapped to typical GM V8 specification; verifying the gap before installation is still recommended.
