Do not install an oil cooler until:
A. You know more about motor oil
B. You know your baseline oil temperature (Install a gauge!!!)

regular motor oil likes temps below 230 F, synthetics 270 F
If you are not exceeding these temperatures, do not waste your time.
On a hot trackday (dragstrip) my oil temps have never exceeded 210 F
(I run Syntec)
You want to keep your oil temp on par with your coolant temp.
