Without - cruising at 95mph in about 90 degree heat my oil temp would stabilize around 260. After putting it back on, similar conditions, about 225. I think the effects of it are less pronounced since it regulates the temperature against the coolant temp which can easily reach 200+ degrees during normal usage... whereas an air cooler will easily get oil temps down to 180's or even lower.

Please take the numbers with a grain of salt, as my car is pretty far from stock. But the 35 degree difference does show that the OEM cooler does make some impact.
Hmm very good to know. My plan is to eventually (before summer) buy an oil cooler anyway, but I was genuinely curious whether or not I'd see a difference.
