after doing research on the forum on o2 sensors it looks like I need to get the oem o2 sensors ,,, question is what is the best price on these and hopefully the dealer isn't the place to go (I hate that place!),I see there are some cross over part numbers, is NTK 11780872674 the only part number I should be getting ? or is there other numbers that will work ,thanks gmonde

 

I think your car uses the NTK 25648. $90 from Rock Auto. $100 at Amazon with free shipping.

You can get Bosch, Denso, etc but some people report problems. The NTK is the OEM part... And is sometimes even cheaper.

The number you have is the MINI part number. If you put that into the Rock auto search, you will see all the choices (pick NTK!)
