...hotter AIR can "hold" more WATER VAPOR, the inverse of cold AIR can't "hold" much water vapor.

...water vapor acts as a "detonation" deterent; BUT, too much water vapor reduces the amount of AIR (oxygen) being drawn into the engine because the water vapor has displaced it (for equal volume, more of onething means less of the otherthing).
