Today I was looking at building my own custom CAI using this one as a model for me to follow. So I printed the page and went out to my truck so I could compare their photos to my actual 4.7L engine bay. As I am looking at my engine I notice there is a square looking box sitting right in the middle of my engine bay. As I look around I notice there are some sensor wires running to this air box thing. What is this sensor, is it necessary? If I were to use this custom CAI would I need to install this sensor in the CAI or just let the sensor wires dangle?
