^^^ not much just a tune up thing to do. If anything it would make it run smoother and improve gas milage. I was just throwin out some beginer stuff for you to get your hands dirty on. I recomend ngk brand plugs cause that's what Honda puts in there from the factory. Don't bother spending a lot of money on real high end ones like "Bosch platinum + 4's" because they tend not to last as long as the Honda original equipment ngk's. You can get them at advance auto parts or autozone.
