Lol! I'm always interested in how this stuff works out. For those that fabricate, sometimes the ideas are good, but the application doesn't work out. I started with the dog house design because that was the type of filter I already have on the Burb. About the only place I could fit that, was back under the hood where the air tends to be warm. So, I got a filter that would fit the wife's Yukon. I figured flatter would work a little better. There is plenty of space under that fender, but it can be a bit of a harsh environment. And, there still needs to be some decent serviceability. Once I build the box, I'll need to figure out how to latch the two sealing parts of it, then figure out how to securely mount it under there. I have the fender brace and the inner to outer fender areas. We'll see if I need to get to the outer lip for attachment needs. Plus I can run a brace off of the inner fender. I don't want it looking too obvious from standing outside of the vehicle. But I need to fit the box, and two lengths of 3" tubing. I want to pick up air from the inner fender just behind the grill. Maybe benefit from a touch of positive air pressure as my speed increases.
