I bought 6 new Motorcraft plugs form FPN about 2 months ago and the car run fine. 20 days latter it started to bog down. Took the the plugs out and 4 of them had crack lines down the ceramic part of the plug where they were grounding to the cylinder head. I went to the local Ford delaership and bought 6 new for over 10 bucks a pice. I lost my recite, so I never emailed the FPN. They either sell shity parts, that is why they are so cheap, or some kind of coincidence that I got 4 bad ones. Car runs fine with the plugs from the dealership and they have been in for about 2 months. Just thought I would give you a heads up.
