Oil Coolers location/types for FI Zs.

I purchased an oil cooler kit that contains the 34 Setrab core and thermostatic plate. I had planned on placing the core behind the intercooler but in front of the radiator. However, I'm now having second thoughts on if this will even be beneficial. There is already minimal air moving into the engine bay. Using this air to pass through the intercooler, oil cooler, and radiator seems like overkill.

So those with similar setups, did you see a beneficial drop in oil temperatures? Did you mount the core between the intercooler and radiator?

AAM is working on a liquid cooled oil cooler. I have thought about selling my air cooled oil cooler and going this route.

Thoughts?

It should look like so:

IC --- Oil C --- RAD --- Engine

I have the 4.5L and two 34 row Setrabs tied together and on an 80* day my temps may see 160-180* peak...
