I've seen some people on here talk about plugs and oil needing to be changed after seafoam, so I waited til those needed to be done and seafoamed so I got their use. So what else should I change now? I got the car about a year and a half ago and don't know when the fuel filter was last changed. Should I do that? And the oil filter needs to be changed with the oil, correct? Oh, and btw, anyone want to reccomend a certain type of spark plugs? I heard that copper are the best but don't last long, also that platinum is a good choice. Anything else that someone can suggest I do to tune up my engine now? Thanks!

 

Yes, every timeyou change the oil you msut change the oil filter! You could change the fuel filter but if nothing is wrong with it you don't have to. If you notice in the manual there isn't a mileage suggestion on changing the fuel filter because they are as crappy as they were in the good ol' days.
