You will have a little room to place the air box because of the belts and fan. I think you will have to turn it upside down so it will seals agaist the hood and runs into the MAF throttle body. So the opening needs to be located between the motor and fan for a straight shot of air. It looks like there is enought room to do it but I am not sure about the short hosed to get the air into the motor. I would see how big the airbox is and if can mount were it needs to be for the hood. Then you need to make sure you can get the hose to work. The opening will be in the front 1/4 of the hood. If you want something bad enought you will find a way to get it done. Just off the top of my head no coffee yet.
