quicksilverdon. I have the stock airbox & the oogah horn from AZ. It fits perfectly on the side of the airbox( between the fender & box, infront of the little 90 deg piece the lets cold air in). So i'm sure yours will ahve no trouble fitting there. With the stock box in place you can barely see it. IT IS LOUD, I scared the crap out of my wife 3 times today, once i hooked it up. She heard it in the house with the windows closed & the TV & A/C on. So being under the hood is no big deal.
I can tell you it WILL NOT fit behind the grill
