Oil and filter change 3000 miles unless you do all hiway driving on synthetic oil. Some non synthetic oils lose effectiveness in as little as 2500 miles.
Air Filter 24 k miles is ok, I do 15k miles.
Plugs every 60,000 miles (for better mpg+ performance) with .NGK Oem Plat only.
Many here do our coolant every 18 months-- a rdaiator can last forever if it is frequently flushed and usoijng no tap water ( mix distilled water w/ the ethylene glycol)
Hmm, I am not sure your I30 has spark plug wires isnt it distributorless ignition? (I amy be wrong am a Q45 guy).
I completly have brakes bled, at least one per year with Valvoline SynPower DOT 3/4 brake fluid ( best off the shelf brake fluid)
