I've been kicking around changing out my stock grills on my TJ. They're pretty restrictive and raise my temps 3c-5c when I put the sides on.

Most of you have seen my rig already but this is what I started with...


Stock grill


Picked me up some specially made New and Improved Mesh from Home Depot


Made some templates of the opening on the side of my case and clamped the mesh between them


Slowly work my way around bending the sides down


Side by side comparison of the finished product


Mounted


Another comparison


And on the case


So, temps now stay the same whether the side is on or not. Now I'm undecided whether I should leave it silver or paint it black? I kinda like the contrast of the silver but I'm sure it would look great black too. What do you guys think?
