seems to work on mine,did some research on the products and it stacked up for me,fell for the marketing!,maybe.
ceramic 7 is an internal engine coating that works in a similar way to castrol magnatec,reduces wear,everything moves that little bit better.
first tried it on an a4 2.8 quat and it seem to make a difference,for example when i started that up in the mornin i got a second of chatter until everything was lubricated,added ceramic 7 never got it again and that was 6 months ago
