I don't think that you can prove a cause > effect relationship between the cams and passing emissions unless you did back to back emissions tests between the stock cams and the S4's.REDSENTRASE-L said:good tip! i dropped the car off and it took em about an hour before they started. so i am absolutely sure it's the cams. maybe i should retard the timing ti help reduce emmisions. i dunno.

yeah sure! i'll even install em for you..............SR20steve said:Just trade me cams, its a easy fix bro.
