Radiator ducting

Besides, a strut tower bar will do way more than anything mounted in front of them.

I got really close to cutting out. I stopped when I realized I would have to make new oil cooler lines. Mine are already stretched pretty far because I lowered the oil cooler about 2 in. so its bottom is even with the bottom of the radiator. What I've ended up doing is relocating all the wiring up underneath the upper radiator support and I've since cut off all the brackets on the oil cooler support. So it's still there and still annoying to get around but it's a lot less intrusive than it once was.

Haven't got oil temps over 180 driving around in the summer, before they would easily get over 200. Also helped lower the coolant temps a few degrees, but never had high coolant temps before adding this ducting.

I was wondering if anyone cut out the "spokes" and center of the lower bumper. I'm considering doing that too as I've also got an ISC splitter, which gives about 1.5 in. more height for the oil cooler/radiator inlet. Are you still using the stock undertray as well? I'd think you'd have to to avoid air rushing around the radiator.
