I have an '05 Titan extended cab and want to explore a little more of the far north in Alaska with my wife. She wants some amenities (like shelter with enclosed bathroom facilities) which means hauling a camper around. So I have several questions. I'm looking to improve the performance and hauling capabilities. Any ideas on some basic improvements I can do in my own garage? I am considering a CAI (we do have a very fine river silt that blows around here, have heard that could be a problem with some filters, also heard some oil treated filters may contaminate the mass air sensor and cost big bucks to fix). I am also looking into a catback system but may need to also beef up the suspension which might keep me from a dual exhaust setup. Anyone out there with a similar situation? Oh and we often experience -40° F in the winter up here . So for a first post....
