That's also what I did as - similar to you - I still got too high oil temps after installing the AR oil cooler (although this one already dropped the temps somewhat). Right now I'd use the ER sports oil cooler that replaces the stock core with one that is double the size. In my case this has eliminated all oil temperature problems for me.

You can see what I wrote about the one I got from them in the thread in my signature - I wouldn't really recommend it. They seem to still make them though, but on special order apparently.
