i have had my dynasty 5 years now an have never changed the air filter the little spring loaded gauge just barley moves dn to 2.50 no restiction at all ,do they last like that, an do i need to change it.put 40000 miles on her.
Ignore the little yellow air filter Gage, they aren't reliable! Yes, you probably are overdue for an air filter change!When to change is mostly a function of where you drive and total mileage since the last change.Your Monaco owners manual will probably have the part number for the air filter. I too have a Monaco product and I do my own air filter change and I get the filter from NAPA truck parts store for about $80....CAT wants about twice and Monaco wanted about 4 times what NAPA gets. It's an easy change out. It is Monaco that designated the air filter part not your engine manufacturer. You're ready, go for it!
Also, air filters are a bit like tires. Even if you do not annually drive that much they will age out because the paper will deteriorate. I have heard both 2 and 3 years for filter changes. At the two year point I will inspect mine and see if I want to go for the third year. I have yet to talk to a mechanic that trust the air restrictor gauge.
As racerchaser said....it's a time thing...and IF the filter deteriorates and becomes unglued and your engine ingests paper and glue thru the turbo, it will cost MANY air filters to fix it!!!
