Here is a list of primary Filters, Fluids & Belts for Entegra / Spartan. Also attached are a few files for further information. First are the Cummins Recreational Vehicle Maintenance and Operation recommendations for the ISX and ISL. Next is a Spartan Motor Home Maintenance guide.
There are some differences in part numbers between these two areas, some of that is due to numbers being superseded, others are Spartan specific choices for filtration. If you are not sure, ask for clarification or contact Entegra and/or Spartan. Let others know of new numbers or errors in the list so we can keep this current.

I assume the new X15 engine will have a change or two from the ISX.
I would expect so as well. Have not seen anything "official" from Spartan on what they are using / recommend for the X15 (500/605).
Next time I get a chance to peeking under a CS-18 hood (so to speak), I'll have to take some notes of what has been installed and compare that to the ISX. I see you have a W on order (awesome floorplan BTW), if you get a list of items please share and I'll be sure to update the first post :)
