I am looking at getting a Catco Catalytic Converter to replace my OE (86 original probably) and am wondering if the Catco O2 Sensors are a viable substitute as well. Has anyone tried these? Obviously, the OE price is what the driving force on this is. Also, if anyone has the measurements for the cat on an '86 325es, that would be great. And does anyone know offhand if the O2 Sensor is the 3 or 4 wire type? Thanks for all your help.
Drive on, Bimmerheads.
