|Kelly ignition harness incorporate a negative-pitch spring design (the tip of the coil spring extends inward) allowing the coil spring tip to lie flat against the spark plug electrode, providing 360 degreee contact. Kelly ignition harnesses are FAA/PMA approved for Lycoming, Continental and Franklin engines.|
Good quality and easy installation. However, the leads wires were marked with a tape Top 1-4 and Bottom 1-4 which is fine but may rub off over time. I noticed on my old harness the nuts themselves were stamped with T1-4 and B 1-4 . Overall good product
