Review on Motorcraft SP 501 Spark Plug by Eddie Sanchez

I don't normally write reviews on products I order from Amazon but thought this would serve as a warning or reminder to anyone who does buy these plugs. Before installing, check the clearance on these connectors. I bought these for my 93 F150 351W as they are the right replacement. Several plugs came out of the box without a gap. Not a big deal as I've checked them all anyway, but anyone who thinks they can just paste them in without checking the gap will be disappointed. Also, one of the plugs arrived in what appeared to be new in the box, but the threads were stripped. I ended up cleaning and reusing an old fork so it wasn't the end of the world but a new product shouldn't be defective.
