N54, Where to buy all 4 02 sensors?

JonEQuest · 09-20-2020, 12:47 PM

I want to replace all 4 of my 02 sensors. I am willing to solder and wire universals to the OEM plugs but would rather not have to. I just don't want to spend $300 for them.

Bosch from FCP. Lifetime warranty. $300 is worth having your car run properly.

FCP only carries "OE Bosch" and "Genuine BMW" with the cheaper option being around $465 for all 4.

I just got all 4 from rockauto

rockauto is the cheapest option, but i wish i would have done fcp so i could get future replacements free

Free replacements are nice. I change my plugs and coils every other oil change thanks to FCP. Well worth it. Haven’t dealt with a misfire in ages.

Soldering O2 sensors is a no-no.

Second Rockauto.

For precat O2s, i purchased the same O2 (17098) for both banks. Same sensor, one is longer than the other, and is much cheaper. Just ziptie the extra slack.

Edit* Just checked, $72 each.

Do our tuned engines with kittyless downpipes tend to eat the O2 sensors? I wouldn't be surprised if so, wondering if I should order em from FCP as preventative maint and replace every x interval to make sure it's running at 100%.

Not sure if they do or don't. I'd probably say they do. If I was a betting man. Under normal conditions, they should last 100-125,000 miles.
