Hi scotty ,I have a mitsubishi outlander 2005 with 150k.I have p0136 and p0141 bank 1 sensor 2.Im guessing the downstream 02 sensor needs to be replaced.I see that denso o2 sensor cost a lot,I was wondering if I could get ac delco and it cost 20$ on amazon direct fit.Would you recommend me getting it ?Thank you

NO, those sensors stink compared to oem japanese ones. seen them not work at all in many cases when put on japanese cars.
