Thread: O2 Sensor brand?

03 GTP. Any insight on a brand for a front O2 sensor for my 03 GTP? Bosch, Denso, Delphi, AC DElCO?

Thanks for the input.

Everyone says Bosch o2's are horrible.

Im using one. I let you know in a year haha.

I worked at O'Reilly in college and sold my fair share of Bosch O2 sensors. I can't recall having a customer come back to complain about them.

I'd go with Bosch FWIW

Denso.

I had a Denso and my fuel trims went out of whack after 3 months replaced it with AC DELCO problem solved.

Anything but Bosch

that's weird that the densos gave you issues. I use and recommend denso cuz like Sven said "Denso = Delphi = AC Delco...they're all listed as OEM suppliers."

Bosch = Dog Sh!t

Probably just got a faulty one as sven mentioned but you cant go wrong with ACD.

Thanks for the input! I learned something, that Denso is OER, same as Delphi & AC Delco. I'll go with either Delphi (already have many Delphi parts with no complaints) or pay $8 more for piece of mind with the AC Delco. It'll be a game time decision.
