I remember looking up a topic about this in the Forced Induction forum and comparing it to the Autosalon mag. one...worlds apart. From memeory, they said that the Apexi is the shitest by far Look it up in AS if you dont believe me.
As for the oil...you dont drown the damn thing in it...besides how hard is it to clean a AFM once in a while ? two sparys and ur done.
