if you have the tools you could make a heat resistent shee4t metal cone to go around a cone if you put that on yur car and then have a 3 inch tube coming off of that and running it somewhere where air could come in. i jsut put an extension on mine and its like butt up against the headlight and it works good
take out the airbox and rip out the insides. That there will open it up alot. Then get the biggest hole saw you can find and cut out as many holes as you can fit(on the lower part of the box, below the filter) then get a k&n drop in filter and you're good to go. I used a 2 1/2" hole saw i had. Worked good. But it won'd do much if you let the internal parts in the airbox.
