Removal process: I first started with no airbox at all as I had the JWT filter removed already. There are several clips on the wheel well that have to be removed. I took them all off up to the shock tower. There are also some screws under the air dam in front of the tire that hold the wheel well cover in place. There was one bolt holding the resonator onto the frame. I forget if I removed that from inside the fender well, or from between the fender and tire, but I believe it was from the latter. The resonator is too large to pull up through the engine bay, so I slid it out through the fender well. I had the tires pointing straight, but it may have been easier with them turned to the right. The resonator had two clips attached to it that hold the fog light wiring in place. I cut/pulled these clips off and feel that my fog light bulb replacement will be much easier now!
Did I tape up the hole? Nope, I figured if it wasn't getting enough air from under the hood, it could pull more from the fender (favorite trick of mustang owners). Just came back from a 300 mi trip and am liking the sound. No whistle, but a little louder growl than stock. And best of all, it's free!
