I have visited this web forum on several occasions, and decided to sign up. I am not new to owning a Grand Prix, owned my 01 since 2005. Currently has 137,000 miles. Just finished replacing lower intakes, upper intakes, upper plenum, map sensor, plugs, wires valve cover gaskets. Only thing I have done to it is add red pinstripes, and added a spectre cone filter. I also took off those ugly factory exhaust tips, and replaced them with 4 in stainless round tips...huge improvement. Otherwise its stock. I have done all the work on this since we bought it, so if I can put my input on helping anyone out...have a great day.
