You'll find all sorts of opinions about this. I went with the standard replacement I bought from www.fleetfilters.com

aklim,
Check out www.proguard7.com it shows why you do NOT want a 4 layer filter on a diesel. The PG7 stops the dirt btu flows the air. Check out the AFE Stage I ans Stage Ii intake system, best value for flow and stopping dirt out there. Call us if you have any questions etc.

I've got some input and another question on this...
My X is all stock..... A friend got me a K&N replacement for free so I figured I'd give it a try. On my recent trip to WY and Back pulling the 5-6000# trailer, I swapped the filters out a couple times just to see the difference. None of the drivers really felt any difference, but it appeared to get me one extra mpg (while pulling, so we're talking 9 vs 10).
Other than the Hellwig I ordered and the new shocks I'm deciding on, I'm not likely to spend any more money on mods right now, but a friend who did the Kwik filter really boasts about it. He had all the goodies though... WW, full exhaust, Diablo programmer, yadda yadda yadda..... My guess is I'm pulling all the air the motor knows what to do with through the K&N and until I open the exhaust up there's no point in putting the bigger filter on. Am I correct, or do you guys think the bigger filter may still do me some good? Would it atleast get me some better sound effects?
Also, how quick is the ECM on these at learning? By swapping the filter every 400 miles, was the ECM keeping up or was I just confusing it, or is the filter really not going to make any difference?
