I extended the rearmost oxygen sensor myself with two oxygen sensors on each side in order for it to plug in properly. I was wondering what I could buy or fix to removed the CEL codes I get every couple of months. Was wondering if anyone sells extension for the oxygen sensor wires or sells the longer version of an oxygen sensor for the rear sports cell cat. Thanks guys.
Go to Bosch site to see O2 sensor wire length's avalability & get the part number. Might have to special order but you will get a better signal.
