I have a K&N drop-in (OEM shape/size) The engine is more responsive, but not more powerful. Keeping the OEM air box eliminates the loud engine intake noise. quiet cabin = happy DW. Air bags? Yes, to level the truck when the bed is packed for a trip, then hook up to the TT and let the WDH do it's job keeping it level after the weight of the tongue is in play. I installed a pair of HellWig air bags ac couple of years ago. It was the only brand that I didn't have to cut off/remove the bumpstops. Direct bolt on, opted for one fill valve since I don't have L or R leaning issues.
