Has anyone had any information about using a K&N air filter on their diesel engines? I have an ISB 6.7 Cummins.

Supposedly K&N are supposed to be more superior than the stock filters.

Most info on the K&N is very bad (filter percentages too low). Others will chime in saying they are fine. I would listen to the majority if I were you.

I beta tested for K&N a diesel filter for almost 2 years, had my oil analyzed and everything was ok. Been using a production unit since they were released in May 2012. There are those that don't think K&N filters are any good but they seem to be working good for me and the tests prove it.

Can you tell me the part number of the air filter you have for your RV. Was that a Cummins diesel?

I have a 5.9

Be aware that the CHASSIS MAKER, not engine manufacturer specs the air filter. All the engine manufacturer is tell the chassis manufacturer the CFM requirements of the engine.
