Intervals for certain maintenance...........Fuel filter, Air filter,...

Just wonder what the general consensus is on changing the fuel filter and air filters on the Tacos. On my s10 and mustang I just change the fuel filter anywhere from 12-15, sometimes every 20k miles. Air filter I just check every few months and monitor to see how dirty it is so might be a crazy question in the air filter regard

Just asking though, food for thought. With the stang, I have a K&N and usually clean the filter around , I try to every few oil changes or so. Any other tid bits you guys want to share maintenance wise or anything else I'd appreciate it

Also, bought the truck in Jan with 113k miles on it and now has 120k. I am thinking about tuning it up sometime in the future. What do you guys/did you guys or when did you tune up and did you do coil packs as well as plugs/wires same time? My mustang is a 95 and s10 a 92 so this is my first vechicle with coil packs
