2010 Ford F150 XLT 4.6 3v
I am replacing my spark plugs. I have a 4.6 3v. I went to the dealership to get a quote on a set of 8 Sp 509 factory plugs. $21.83 each $174.64. That's a good chunk of change, but I have always heard that you should use the factory plugs. Here is where it gets interesting. One day while on the Wish site I see a set of the same factory Motorcraft plugs. 8 for $33! Now I know if it sounds too good to be true it usually is. Have any of you tried these spark plugs, or any opinions for or against using these?
