I'd like to start by saying thank you for the years of advice and pointers I've received from you guys. This was always the first place I came to when I had a question and I never failed to find someone else with a similar experience and an answer. I just ordered my new 2500 6.7L CC long bed (this will be the third one I've owned others were '95 & '06. Took both to 200K+ miles) and am looking for suggestions for an air filter/ cold air intake. I work in real dusty conditions and am looking for the best filter or cold air intake for that. Also any suggestions for a leveling kit or pics of truck with 4" front lift and 2" rear (what do you call that a 2" or 4" lift?) would be appreciated....thinking about possibly going a couple inches higher with this one, in the past I have always just leveled her out. I will be running the stock laramie wheels with some BFGs on 'em. Thank you in advance for your help.
