In my case in my opinion is knock. That sound is knock. My last 3 fuel tanks I used 91 oct. On Wednesday night put a full tank of 93 oct and the knock disappear. Yesterday I change sparks everything was fine but during the afternoon the noise appeared again. The temp was close to the 90s. If it's knock something still needs to be done.
