So who can tell me about these quik fire o2 sensors?? are the really that or a sensor thats use is for something else that others are puting on the V's??? I been in the car bussiness a long time but never ran across them,,, doesn't mean that they don't exist but I am curious.... plan on putting headers on hopefully this upcoming winter and heard it was good to use them,,,, so any info would be appreciated....thanks
