Cannot comment regarding engine component effectiveness, but have had experience with brake rotors. All I can say is... it works!!!
Tested them on a fleet of ambulance who had an above average appetite for brake rotors. These guys were getting 2100 miles out of a new set of rotors before they warped or turned blue. A noticeable improvement in both durability and performance with the “frozen” rotors we sent them and no disadvantages (aside from cost).
Check out

So has anyone cryogenically treated their golf clubs yet?
