The spark plug end has a terminal that snaps onto the end of your spark plug so it will not ever come off or get loose and sloppy. Make sure when you install them you feel it snap into place.
This wire set will fit the 316, 318, and 420 John Deere garden tractors.
These are a set of two plug wires (one for each side) to fit John Deere P series Onan motors (P216, P218, P220, and P224).
