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 I need to gap the iridium spark plugs before installation? A: No, the iridium spark plugs come pre-gapped from the factory; however, it's always safe to verify the gap matches your vehicle's specification.

Q: Will this kit fix my P0300 random misfire code? A: If the misfire is due to worn coils, plugs, or wires, this complete kit often resolves P0300 and cylinder-specific misfire codes, but a diagnostic scan is recommended to rule out fuel or mechanical issues.

Product appearance and specifications may vary slightly by batch. Compatibility may vary by serial number. Verify fitment before purchase.
