These spark plug wires are made rather well, even though I accidentally ordered the wrong gauge.That being said, I can't speak to how well they work or how long they'll last. Which is why I only left 4 stars... But, just from handling them and testing them I can say they will likely be a solid replacement for the correct application!

This 10.4mm spark plug wire kit is designed for Harley Davidson Big Twin models from 1999-2019, including FXD Dyna and Softail. The thick insulation helps with durability and performance, potentially improving ignition efficiency. While installation is straightforward, some adjustments may be needed for a perfect fit. A solid replacement option for those looking to upgrade their spark plug wires.
