O2 Sensor brand?

[Mr D]

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.

Denso = Delphi = AC Delco...they're all listed as OEM suppliers.

I've used Bosch and never had any issues.

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.

That can happen with any part. Things can be defective right out of the box...that's why warranties are awesome.

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.

Normally I'd say Bosche, but I'm second thinking that now after all the negative feedback. I used one, but it was for my rear O2 which doesn't do anything besides check the cat for proper operation.

So I'd just go with ACDelco.

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.
