I don't really have a history of what has been maintenanced on my car as I bought it with 30K miles on it back in the summer. I want to be sure I do all the necessary maintenance while it sits in the garage this winter. So at this mileage, what should I go ahead and replace? I Seafoamed it last week (= )and of course changed the oil a couple of times since purchased. I have Zero mods to date (well, unless a K&N drop in and silencer removal count), and other than gears and shifter, I doubt I'll do much to this one. I just want to keep it in top notch shape, but I'm a mod-motor "virgin".
