I didn't do the actual Newmission mod...I didn't enlarge the port on the bottom of the air box. I simply used a 2" flex hose...I routed it from the box down to the lower portion of the grill area. I realize that's a small diameter but I don't want to modify the box just yet...I've only got 9700 miles on the car and don't want to overdo things yet. I can already tell that the typical acceleration lag on this vehicle is pretty much gone. It truly runs smoother on the highway. I plan to figure a way to flush mount the hose in some manner.
Any thoughts on this?
