i got a 6th gen sedan, 4 cyl. I plan on doing a complete tune up. would you guys recommend i take it to the dealer and let them do the work or do it myself. I'm getting plugs, wires, cap & rotor, pcv valve, tranny fluid, radiator fluid. I got all the tools and equipment at home to do the work myself and I've done it many times before on my other cars. so is worth the extra few bucks to take it to the dealer or might as well buy the parts and spend a few hours doing it myself?
