Open yor hood and remove the hoodliner, you will see a cutout area. The hood scoop is aprox 2 inches larger than that. I am sure someone will go out and measure there's for you so you have an accurate measurment
If your willing to wait till the end of Oct/ early Nov ill sell you my factory scoop. I'm getting a shaker scoop so my factory scoop will be on the market. . Shoot me a PM if your interested.
