Budget K&N Air Intake Mod +'s, -'s, ?'s

[tjkj2002]

Tjkj would you recommend replacing the O2 sensors at any particular mileage? Would that help with mpg's?

They typically last about 100k.They can fail in many ways and the most common is the heater going out or they become full of carbon making them "slow" which both will throw a code.

Okay so I take it then if the jeep isn't showing any codes then they should be good.

So, changing air filters is not necessary then. Just blow the dust out of the old one and it should be fine?
