"dennis45"....I had the Donaldson on my Monaco. I liked that I could actually look at what it had filtered when I replaced it, plus it was cheaper. I'm trying to find a Donaldson housing that will fit my new coach, but it looks like it would take a redesign to do it.

None of those test were with the K&N washable HD Diesel filter that uses NO oil for a filter. That can be used on all DP MH's.

A complete different filter then the one made for gas cars, motorcycles, pick up's and MH's.

I have looked a number of times but the actual test results don't seem to be published. Can you point me to a statement that lists the "efficiency" of this filter? All I can find is this statement:

Tried and Tested
Each commercial grade diesel air filter design is tested with Fine Grade Test Dust using the ISO 5011 air filtration test protocol to determine filtering efficiency and dust holding capacity. K&N commercial grade air filters are designed to protect vital engine components even after the filter has been cleaned multiple times.

My 99 V10 had one on it when I purchased it. Now I am thinking maybe I should remove it and go back to the paper air filter.

I probably would have to replace the complete housing filter.

I used K&N filters for a while in a V8 and a V10. Too much fuss and mess for me. I went back to using a good quality disposable filter.

I used to be a vendor for K&N. I was their powder coater for all their metal brackets and parts back in the late 90s. They build a quality product for what it is. I've used their filters for years but I won't put that kind of money out for my DP. I'll just buy a new air filter every 2 years from Ecolite and be done with it. Increase in fuel mileage and increased HP? No not really. Their engineers dyno different units and it might increase the HP in a controlled environment but not enough you can tell in the real world. Don't waste you money

Did you have to replace the entire housing?
