Motorcraft Spark Plug - SP546X

I ordered these plugs for my 2007 5.4l F-150. I ordered 8 pieces at once in one order that arrived on different dates via different carriers, 3 of which arrived in one shipping package, while the remaining 5 arrived separately!Upon examination, I found 1 plug to be different and made with low machining quality. Also it's packaging looked suspicious. It had no manufacturing date and time on the inside of the carton as the others, the QR code on the outside was printed not unique nor stamped, the bar code was different also. As to the subtle observations: the top metal knob was poorly casted and not concentric with the porcelain, the texture of porcelain itself was not even, the ground gap was not correct, and the turning marks on the lower part was not smooth.I hate to delay the job for one spark plug reorder, which is inevitable since I will definitely not use it.

Thank you Amazon for getting my spark plugs for my 2007 F150 5.4 they are a exact fit for my truck!👍

Genuine Motorcraft

Just got it in works great

The packaging was less than expected. Plugs were not in the box of 4, just loose in the shipping bag. I know the product so that's good don't look damaged atm.
