It useless but provisional in it use and worth. (Both items.)
As mentioned, on an air gap style intake, I see no gain. On a stock intake, there could be something there. I don’t think much of it. For Street duty there may a plus in there.
When does a slightly cooler intake help?
Cool can useless?
Ummmm, no. Like above, when does cooler fuel help?
A bunch more than an hot oil shield I bet.
