No mods on a 4 cylinder will enhance reliability. Common upkeep is simply the important thing.
On a 6 or 8 they might? Why the excellence?
OP, because the automobile is inventory, I can solely consider a freer flowing exhaust, or perhaps bigger radiator and intercooler should you monitor / drive aggressively on a regular basis.
In any other case, get the very best octane fuel you may, and sustain with oil/filter adjustments as talked about.
