SoCal2v is correct, the maf meter goes into the fender with the air filter facing down. You might have to cut the wire harness bundle that your maf meter wires run into to get more slack (I did not but some people do). Bolt the maf meter to the pipe, slide it threw the fender and then bolt your filter on from the bottom of the car, then plug your meter up. I had the jlt cai on my 02 in the past.
