Before u upgrade anything. U should make sure everything is functioning properly. Always use good oil. Change at its proper intervals. New plugs and wires. I wouldn't worry about coils unless your having issues. Check air filter replace if needed. Also I would use some carb cleaner. Check for any bad vacuum lines. I would remove you air ideal assist valve and clean it and the bore hole out. Also a tranny flush and filter wouldn't hurt at them miles. As for coolant upgrade to me tel elbows and flush system and use green or yellow. Forget that red crap. Check your motor mounts. That's just some of the things I recommend you do to your care as some preventive maintenance.
