Got a P1147 code for bank 1 sensor 2. OEM O2 sensor at the local stealer**** is $250. Bosch is $68 on Amazon. Need opinion if Bosch is ok.

Thanks,

I'd go with Bosch. OEM sensors are Bosch brand.

from my experience the MAF is the only thing that I could really tell makes a difference when sticking with OEM sensors or coils. I had picked up a used OEM MAF and my engine ran way better with it compared to the Duralast one that I got one day because I needed the car fixed ASAP. I ran Duralast cam sensors and coolant temp sensor for years on my original engine with no issues. I've been running Ultra Power ignition coils and Oxygen sensors with no issues as well. I mainly avoid buying unbranded Amazon or Ebay parts, you never know what you're really getting. I have had good results with stuff I get from Rockauto and I never pick their cheapest option. I remember a few years back hearing about counterfeit spark plugs being sold on eBay and Amazon SMH.

I used Bosch for both downstreams. They work well.
