Installation Notes and Tips

Confirm the female terminal style and 115-degree boot orientation match the original setup on your Ford E-250 Econoline Club Wagon, E-350 Econoline, F-250, or F-350. Inspect plugs, cap, and coil components during installation to avoid carrying old ignition faults into the new wire set.
