Air Filter for ISL 400 in 2007 34FDDS

[Rick J Fisher]

I need the correct p/n for this filter. In an old post, Engineer Mike says AF22249 but Filterbarn does not recognize this number.

My two cents on oiled filters such as K&N: Been off-roading for many years and have used K&N filters for off road and on road vehicles. The problem with using an oiled filter on-road is that they don't get enough dirt and the oil gets sucked through pretty fast. Off-road, they get clogged fast and so you clean and re-oil them often. I was surprised to find a dry and quite porous K&N on my motorhome after a few thousand miles. I now use dry filters both on and off road.

No info on the K&N.

There should be a number on the old one, if it's not to be found. I can look at my records, it should be the same as mine.

Rick,

I think the correct filter number is AF25549. At least that is the number for my '04 with the ISL 400, and the number I found in one of EngineerMike's previous posts. I got mine from Ryder Fleet Products.

I have a FillPro & Fram cross ref but stick with the Fleetguard filter. Why take a chance on a dusted engine. Ryder Fleet Products excellent source:

Been in the heavy duty filter distribution business for over 30 years. The short answer is dont use anything but a dry pleated paper element in the filter housing that was included with your coach. They work very well and will be sure to not "dust" your engine.
