Ok so ive been reading and everyone says bosch is bad. I called my local parts store and all they stock is bosch and its for 64.99. I called another shop and they have one called delphi for 67.99. Has anyone heard of delphi? Are they reputable as far as 02 sensors? No one has denso and the ac delco brand is 150.

Go to Auto Parts Fast at RockAuto and look there, you might be surprised at the price, even with shipping.

Bosch parts are Not necessarily bad. It'* the Bosch spark plugs that mysteriously sometimes are ok, and sometimes not ok on GM cars in general.

but would u trust a bosch upper 02 sensor? Does anyone have one on their bonnie?

bosch is just fine. dad is an auto tech and we've never had one come back on us....

Don't use a Bosh O2. I personally have never used one, but other members have. And they seem to last about a month or so. I have a Denso in my car.

delphi is what we sell for fuel pumps....good brand for fuel pumps. been a good company to deal with id imagine 02 sensors from them would be good too

nvm bought a denso 02 sensor from rock auto. 44 bucks shipped for 3 day delivery..NOT BAD AT ALL, the local auto parts stores in my area wanted 64.99 for the bosch. THANKS AGAIN~!
