I bought Accel 300+ Ferro-Spiral ThunderSport Wires, part number ACC-7966B from summit to go with my accel u-groove plugs. Way better than stock, but I have not tried the ford racing ones because I heard they were a little difficult. I like the accel ones and had no problem installing them and not a single problem so far. they fit just like they're suposed to, no popping out or anything, plus they have different colors to choose from, I got the blue ones hense the b on the part number. I have a 96 LX 2.5L Duratec Contour.
