There is sufficient anecdotal evidence to warrant purchasing the cool collar. And I'm gonna order one. Just keep in mind, we mustn't expect results akin to those on the Vette given by the manufacturer because our volume of oil is probably at least double what his is. Since we're dealing with a greater volume, we cannot expect the same results--but like anything else, you weave your improvements a thread at a time. If the cool collar helps a little, well, then it's worth it for the cost.
I'm gonna go ahead and order one.
