What bolt on stuff does anyone recommend for more power. Cold Air Intake! bigger exhaust? Any recommendations for a CAI? 02 XLT 4X4 Ranger 4.0 SOCH.

If you want to waste time & a couple hundred bucks for BragadociousChromeDecor, then buy+install a custom ColdAirIntake\CAI from K&N or the like.
Factory stock CAI is actually as good as it gets for the V6~4.0L~SOHC, as it already draws cooler air from in front of the RadiatorFrame.
Only recommend replacing stock AirFilter FordMotorCraft# fa1658 = 8i790W*7i580L*2i280H
with a larger Wix# wa6734 = 9i055W*7i598L*2i441H which still fits in the stock CAI FilterBox & maximizes the filters surface area.

Yes, as said the Ranger factory CAI already supplies 200% air flow so takes awhile to get filter dirty enough to effect performance
The "cone" type filters need to be cleaned regularly, just FYI

Many like the "sound" of 3rd party CAI
Ford CAI is quiet
But if you can "hear" air flowing that only means there is now more turbulence in that air flow, so..................

If a bolt-on part helps performance then Ford would have bolted it on, like when they added the CAI with fuel injection, lol, car makers SELL performance

If you run 91 octane in a 4.0l SOHC you will get better performance
The 4.0l SOHC runs 9.7:1 compression ratio, so WILL ping/knock on 87 octane, so it has a Knock Sensor that changes the spark timing to prevent knocking, this reduces power
If you run 91 octane then no reduced power
