yeah, I've flipped back and forth on this issue as well. If I were offroading on dusty roads, I would run a stock (not fram) paper filter.

Keep in mind your EGR valve is routing sooty diesel exhaust gases directly into your intake system, so I fear that crap more than K&N filtered air.

It's something to keep an eye on but at least soot and exhaust gasses are not abrasive and will burn up in the engine. However, fine airborne dust like you get off unsealed roads is mostly silica and that is highly abrasive and stays in the engine if and until the oil filter picks it up.

Re: K&N Panel Filter on CRD

I used kns for years until I came across a thread on lost jeeps that showed the kns at the very bottom of the particulate filtration efficiency list. You do get more air with the kns

I just wish there was a true cold air intake system for our Trucks. Would love to hear that turbo scream like I do on my transport lol. I noticed an increase in fuel milage once I put my kn in. I run the highways when I'm home in Ontario Canada around 125/130 KPH so that's 75/80 MPH for you USA guys and I get a solid 7.5L per 100k which I think is awesome. We went to Florida last feb on $250 bucks of fuel each way and with all the running around we did.
