I picked up from Lowe’s, a 2-1/4” x 42” piece of foam weather-stripping for window A/Cs for about $2.



It fits perfectly, wedged between the box and fender on the side, and between the box and the Radiator support. Starting at the vertical side near the coolant tank, I then moved horizontally toward the front, and around the corner toward the radiator.



About midway of the box, there is a perfect vertical flat piece to wedge against going down toward the inner fender to complete the seal. This final gap is wider than the others so, just fold over the remaining strip to double in size.



It’s just the right length with no trimming involved and nothing but cool air for the intake.



I’m going to run it tomorrow and check for a difference, it’s been pushing 100*f daily here now. I may still need to cut some additional inlets in the forward facing side of the box, we’ll see.
