What is needed for a tune up? 89 525i

[misfortune]

Well I've ignored my car for long enough and its time for a tuneup. Its an 89 525i. My mental list includes, oil change, spark plugs, oil filter (ofc) and air filter. What else should I change/check?

dont forget to change your fuel filter and run a injector cleaner through the tank before your oil change

control valve, clean throttle body. check crank position sensor gap and make sure its not loose. Check belts and hoses, fluid levels. Depending on mileage on the car it might be time to change the oxygen sensor.
