really? if they use s3 plugs (modded) for the stage 3 kit they have, then thats good news cause of the problems the rs4 can cause... rough idling and black smoke
I've been told by an ex-APR engineer that the APR stg 3 kit uses RS4 injectors, but they managed to get them to more or less behave with software.
