Chicken, I literally bolted on the late model oil cooler/bracket/scoop to my '06 Ss. I can't remember anything being difficult about it? Get new clips. They stretch when removed and won't hold against the flare on the line as well, you sure don't want those lines to fall out

I also did zero testing or temp datalogging before/after Wish I did. In hind sight, I think I'd just run an even bigger aftermarket cooler if I lived in such a hot place again. The difference between the two OE coolers seems really minor side by side.

For 4 bucks, I got some different versions of these:

I meant to mount it in the stock cluster and monitor voltage and oil cooler output temp. Never got around to it... and now I just "Live Data" from ECMDroid oil my phone. New tech! Haha.

Anybody want one? I'll ship it to you
