I purchased the dejon 4" and It works and looks great den. Worth the price

Please dont spend $140 on an SD intake if you are remotely handy with a hacksaw..

4 inch aluminum 45 - $28.95

4 inch EPDM elbow - $14.95

4x6 air filter - $29.95

Total - $73.85 - much less than that if you already have a filter.

Cut the 45 degree elbow right after the bend and paint it whatever color you want with a rattlecan (I used black thermotec paint because it dries fast and insulates), grab some 4 inch worm clamps from autozone since it's non pressurized and voila - you have a custom 4 inch intake.

Here is the one I made for my car - grant you I used an existing 4 inch AEM filter and t-bolt clamps but still..
