Includes intake MAF (shortram) piece. No airfilter is included. It requires a 3" ID cone or cylinder type airfilter. Very nice core. High density turbulators (little fins) on both charge air and ambient sides. Smoothly cast endtanks. Stainless steel IC piping. Fits well. I had no trouble getting everything to line up. The general design is good. Hoses seem to be high quality. T-bolt style clamps, as opposed to screw type clamps. You can put a LOT more torque on a T-bolt clamp to seal the hoses to the pipes better. The clamps are stainless with a gripping nut (plastic tip on nut so it won't come loose but can be turned with a wrench).
