Does anyone know if the ED shared the air filter with any other RAM truck? I want to by a K&N but they do not make one specifically for the ED yet.

I looked at wixfilters.com. They show the same part number 42725 for the ED, 3.6 V6 and 5.7 hemi. I will order the K&N and install it.

I would strongly suggest staying away from the K&N. I tried one on the Cummins engine I use to have, the turbo could suck the oil out of the filter leaving nothing but dried media.

I was a Mechanic for Cummins for a few years. The number one cause of failure in the 5.9 and 6.7 is people running a K&N filter and sucking in dirt after the turbo has sucked out all the oil out of the filter and causing high blow by.

i bought my truck with a k&n filter, and the only way I've found to keep it oiled is to clean & re-oil it every oil change. But your call, some swear by them, but many hate them. I wouldn't have put it on the truck in the first place, but it has over 220k miles and has absolutely 0 blow-by.

Thanks. Any recommendations on an alternative?

I have also had good luck with amsoil filters on my cummins. I might try one of these.

I can't find the link now, but I have read an engineering study on aftermarket air filters. Disturbing results for every one they tested showed that the only way to flow more air is to offer less restriction - in other words, don't filter as well as a stock filter. The aftermarket filters also loaded quicker than stock when dust was introduced to the point that shortly after a new filter is installed, it actually flows less air than stock. I'll keep trying to find the study (I think it was on a Cummins forum). I'll NEVER put anything but a stock filter on my truck.

Never went wrong with any Amsoil product! GREAT PRODUCTS. I have used their motor oil and filters (and 2 stroke snowmobile injector oil)for 12yrs and go extended intervals and never have had engine issues. Usually 20-25k miles or about once a year. Hardest thing is remembering to check it for level now and again.


Don't tread on me!

A diesel does not wear well with dirty fuel and dirty air.

Use OEM unless positive your replacement is at least as good.

Great article. Confirms that I will never buy another K&N again. Way too much dirt passes to the engine. And what a hassle dealing with the oil. Don't know amsoil but looks to be in a similar boat as K&N. I am sticking with stock filter and change it regularly.
The Amsoil filter used in this test was a style that they discontinued many years ago. It was an oiled foam filter.

Another filter that seems to do an exceptional job is the AEM DryFlow, I feel pretty confident that the AEM and Amsoil are the best filters out there.
