Does my V70 xc B5244T3 use 1 or 2 sensors? Does Bosch make a generic sensor w/connector for this engine? Aftermarkets are very expensive.

Usually there is one pre-cat and one post-cataytic converter. If you don't have to pass emissions, only the front once influences the mpg. I had luck and read good things about NGK (same thing with NTK) sensors of Ebay for round $100. Just make sure to get the exact one for your engine/year
