i need to replace my rear O2 sensor, and will replace the two front ones on my Y since there old n-e way. what are best (as in performance and not going bad) and cheapest place to get. the mechanic and the performace shop/garage told me not to get the bosch ones cause the civic guys always blew right through them, will it do the same for the max. he said to go with the oem ones. need help, gas milage sux. thanks

 

Bosch is OEM ...

 

yea, get bosch, once again the max is fpicky, stay stock w/ these, you wont get any performance gains w/ others, bosch are cheap too

 

can you use other brands like Walker, that's the one that buyoxygensensors.com sells.

 

I bought the front two from them.
The ones I got from them were manufactured by Denso,talke to them and they said walker gets them from Denso you can save$25 each if you just use your original connectors.
I did and had no problem,$78.oo for both, came in three days, I live in philly.

 

You do not have to use Bosch,, read up on Denso!! your choice though.
