Bill, are you aware of exactly how that "cooler" is made? It is basically like an old time cartridge filter where you take the end cap off, remove the cartridge, clean out the canister, and install a new cartridge. Most of the industry abandoned those contraptions back when I was a youngster in favor of the spin-on filters.
Since you still retain the regular spin-on filter with this Fueling "cooler", you basically have two filters. Why would you think you need two filters? As for the "cooling" feature, if you look at this thing closely you'll see that it's just some fins on the outside of the filter canister. You can buy similar finned add-ons for your spin-on filter. Trust me, this thing isn't going to do a whole lot of oil cooling, especially when compared to a real multi-row heat exchanger like the available cooler from H-D or better yet the 10 row cooler from Jagg.
