Hey guys, I'm about to do a tune up on my 1991 Mustang GT 5.0, which is all stock except for the K&N filter and rims, and I need some help picking out some parts. For spark plugs im getting the autolites w/ the copper tips, but for spark wires and cap/rotor i dont know which one to get. should i get ford racing wires (9mm)? do they fit perfectly because i read someone here that the wire from the distributor to the coil doesnt fit, is that true? for the cap and rotor should i go ford racing, msd, or this unnamed brand on on cj pony parts? the ford racing one is aluminum while the msd is copper it looks like. any suggestions and/or opinions would be greatly appreciated. Thanx guys.
