Ya I have a 2002 wrx and its got like 100,000 miles on it and it never had a 90,000 mile tune up and its got stage two set up with out the cobb ap yet. But I know I need to get it tuned up The dealership wants about 600.00 to tune it? I was wondering what exactly the dealership would do to my car? Like new plugs, belts and whatnot? Anyone know if I could do the tune up myself for less money? I just need to know what to replace!!!! help me!
