I just replaced my front o2 sensor..got a bosch or w.e for 8x.xx from oriellys. was suppose to be plug and play,but my plug was different for some reason..so i just spliced my old plug onto the new sensor..works fine.
and also I could be wrong but looking through about 5sensors at oriellys desk..The front wont fit the 2ndary sensor.The plug is also different and the cable is alot longer..
so the 2ndary sensor cable is to short to reach the front plug..
Or thats the way it seemed..my 1st o2 sensor has a really long cord..My 2nd CAT sensor is very short cord?
regarding O2 sensors, if I were to replace stock manifold with aftermarket headers, which brand would have the opening for the 02 sensor. i've heard DC and megan do. Which do you guys reccomend? I drive a 99' EX sedan. thanks
