Please don't subject your engine to a K&N Air Filter

Got a new (to me) 22 3500 DRW 6.7 HO Aisin. Changed to a K&N as I have in all my previous vehicles. Started regenerating WAY too frequently. Found this thread and learned a thing or two. Changed back to stock paper filter and everything returned to normal. I don’t wanna wade into the merits/drawbacks conversation. I’m curious, however, as to why the regen frequency changed with the k&n. TIA.
The sensors that detect intake air flow seem to be overly picky on these new trucks. There has been a TSB on intake codes early on in the 4.5 gen production but none since. Any disruption seems to make the truck throw a code. K+n let fine particle and oil by when they are new leaving a dusting on the already post menstrual sensors. It’s a good idea to use factory filtration. There’s plenty of air for even modified engine needs. It’s a cold air intake right off the showroom floor. Excellent filtering media as well. No room for improvement seems to be the consensus there’s really no point to fix something that is t broken.

Thanks for he education! Exactly the info that I was looking for!
 
I recently purchased the K&N Dry Filter for my 24 Cummins - Have always use K&N on my other vehicles and never had an issue.
I have put a few hundred (200 or 300) miles on the filter already

On to a serious question - Running a different air filter - Do you think it could cause the truck to Run More Regens then normal?
Reason I ask is that I only have 1400 miles and it has already done one Regen which was shortly after I replaced the stock filter with the K&N Dry Filter and according the gauge it is probably getting ready to do another one since its over the 1/4 mark on the DPF

Yes it can

Yes other filters are known to cause more regens.

The truck will regen every 24 hours of runtime (since the last active regen), so it’s possible your 1st regen was a timed one.
