Stock O2 sensor is narrowband (only tells you if it is above or below stoich). Aftermarket wide and sensors tell the AFR more accurately.

Yes, you can put a WBO2 in the stock bung, but its recommended to run it further away from the turbo, but not more than 36", and before any catalytic convertor.
