02 sensor???

[emmanuel2112]

So i went to autozone to ask for a price on the o2 sensor and they teling me its going to be 300 bux's. Its that a right price for he downstream sensor?? Just asking cuz i dont want to get ripped off. if u can get it cheaper anywhere else let me know

yup its right around there u can get it between 250 to 280 but its expensive i got a bosch universal and wired it in for 80 dollars but a direct plug in o2 is really expensive

whoa, you can get a wideband with a narrow band simulator for that much, in fact i have one.
a plx-m300 i belive is what its called, im willing to sell for a decent price, it cost me 300+ shipping and it has never been used
