This question may have been asked some where else on here but I did see a debate a while back on another site about when it is recommended to change filters on the Airdog systems. Some guys say everytime you change oil some said longer. Just curious what you all think or recommend or even what the factory recommends. I am sure I havent changed mine anywhere as soon as what most do......I have over 25,000 miles so far..

 

I have a fuel pressure gauge post filter, and I only change the filters once pressure starts to drop. Can be anywhere from 15k to over 35k depending on the quality of the fuel.
