Cummins 400 ISL diesel particulate filter
I am getting a new to me 2007 Itasca Horizon DP with the 8.9 Cummins ISL 400hp engine. The EPA 2007 rules required a diesel particulate filter. Was that a requirement on 2008 model year or 2007 engine...

drwwicks, on second thought, your new coach probably has a 2006 chassis which may very well have the pre-particulate emission engine.
I think they called the ISL's with the particulate filter, 425 hp Cummins (I could be wrong). Ours was called a 425 ISL.
