I think if you do a lot of riding in hot temp it can not hurt, I installed one as have you ever noticed every bike over 88 has a cooler instaled from HD, and believe me they would NOT add cost like that if it were not required, so I guess I'm saying stock the cooling is adequte, but if you ride in hot weather and plan to keep the bike 100K, I think you can justify the cost, or if you trade everyother year forget it.
Worth every penny I paid. I ride in the heat of Central Texas. Before I installed the cooler, the heat management system would kick in and almost stall sitting in traffic. It hasn't happened since.
HD put the cooler on the stroker "Big Inch" motors because they generate more heat. Big chambers run hotter. The cooler only works while moving. It does add about 1 quart of oil capacity. Personally don't feel an 88 needs one. I'd go a good oil temp gauge (not one of the dip stick gauges) first and see what my oil temp was running before investing in the cooler.
They are useful if you live/ride in the heat.
There are good ones available form the moco (newest version) and jagg. The moco unit mounts low in front of the engine while the jagg unit mounts to the down tube. neither is a difficult install.
Be sure you get a real cooler and not some cooler wrap for the oil filter. Also be sure to get one with a thermostat so the oil won't flow thru the cooler till it gets hot enough.
I have one and think it is the best investment I have made, I ride in southern cal where it is hot and alot of stop and go traffic. My temps are lower running with the oil cooler than without.
