Well, There's always the option of removing the front half of your airbox and clamping a cone filter in the back half. You can then fashion some stiff cardboard or other material which is easily workable and cover with aluminum tape and secure in place to block off the hot air from the engine compartment. Then you can remove your high beam headlamp right in front of the new cone filter. This will give you some cool air. Leaves a bit of a nasty looking hole, but it can be covered with a black or chrome grilled stone guard. 7 inch I believe, you'll have to measure. I really don't know if you get any horsepower gains, but it does sound better when you get on the gas!! Have Fun!!
