I think about this every time I change oil. Running TTI's with a Napa Gold 1085 filter. The thing to consider is that oil is constantly flowing through the filter. I don't believe it has much time to heat up. I don't run an oil temp gauge but my coolant temp has never been even a minor issue.
Unless you have a known oil temp issue, don't waste your time or money. Drive it like you stole it, brutha!
Thanks Ironmike- my temp gauge is never an issue either. But my filter heats up to the point of leaking out the seal. I don't want to tighten it to solve that issue, or it'll cause another one...an oil filter that's permanent. (haha)
