i have a 95 gsr w/itr 0025 pistons aem cai jdm itr4-1 header 5zigen fireball cat back i need a new oxygen sensor should i stay with oe or will bosch etc work just as well thamks

 

any narrow band with the same number of wires will work fine, they are a standardized part.

 

FWIW, I had tried two generic Bosch sensors. The first worked for a few weeks. The second not at all. Electrically I'm sure they're similar, but there is a definate physical construction difference. I went with the OEM type and it's been OK for over 18 months so far. You can try the cheap generics. If they don't work or quit working, you can get your money back if you return it. They are subject to the emmissions warranty requirements.
