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.
The filter tested from Amsoil in this review is 10 years old now, and is an old oil media. Good article and comparison, but Christ it's a decade old.Here's a link to the study referenced in post #12 above that compared K&N and other aftermarket filters to a stock AC Delco for a Duramax diesel. K&N Air Filter Review - Debunking the Myths (and why OEM is better)
You guys can do what you want, but again, I'll stick with OEM.
The Amsoil filter used in this test was a style that they discontinued many years ago. It was an oiled foam filter.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.
