I recently bought my 2003 Focus LX 2.3 Duratec PZEV. Its a 5-Speed and a big change from my gas guzzling 72 Pontiac GTO. I just could not afford Gas. I have done a few mods such as new exhaust and STEALTH CAI which I love what other cheap MODS could I do to squeeze a little more out. Plugs, wires, ETC. NOT LOOKING TO SPEND MUCH!
