The reason for the fuel filter is that it could be partially plugged, restricting fuel flow at higher RPM's (that's what happened to me) I bought the new filter at the ford dealer. I don't know about the plugs being better, but mine were wasted after 30 thousand miles, probally because of bad gas. It's worth the 30 bucks or so to do it, then you know it's right. I also had 3 different tunes from different tuners. The six pack offer still stands. My times are from lots of work, no baloney, but I didn't get there untill I changes the filter and plugs along with mobil 1 and a PHP alt pulley.
