Check the listing for details. Buick Grand National / GNX Oxygen Sensor O2 Genuine DELPHI / GM. Condition: New. Listed at 28.00 USD. Up for grabs is a brand new GM//Delphi O2 sensor. This is considered the better ''GNX'' sensor. If you're running a parts store Bosch O2 and having drivability problems, this might just sort out your car. I've had 0 luck with those in my personal GN. The O2s are superior for people that are having a hard time with fueling and have a Bosch sensor. They aren't 100% impossible to lead foul, but they do have a track record of working a LOT better than cheap store brand O2s. Since the Denso's have been discontinued, these have proven time and time again to be the best narrowband sensor available for both stock and hot turbo V6s. Shipping is one flat price for the first one and then any additional sensors ship for free.
