S4 hydro carbon clean


Registered User
I've seen many decent reviews on the engine carbon clean using hydrogen in the intake. I know cuppa who has an s5 v8 is doing it and has proven some good results, but has anyone had it done on their v6 s4? Cheers

I dont our engines suffer from the same issue as the v8's and dont seem to lose power due to carbon build up.
