For Sale Unused SP-542 spark plugs (Qty. 6)

This is for a set of unused Ford Motorcraft SP-542 Spark Plugs. They have not been gapped to any specific gap other than what they come with when ordered from Ford. If you are comfortable and able to, feel free to gap them to your specific requirement. I will not perform any gapping on these for-sale plugs.

Asking $40 for the set of 6 which includes shipping at my cost. Will likely be USPS Priority in bubble envelope
