Good buy.
Worked great. had the anti seize on the threads, and plastic wire holder / spacer. plug fit. Didn't want to take a chance on cheaper. A five minute diy if you buy the slotted socket set and don't have major rust or access problems.

Perfect OEM replacement
Perfect fir for my 2005 Armada, it was a plug and play much cheaper than the $156 cost at the local auto parts store. This cleared my P0057 code which is the Bank 2 downstream O2 sensor.

At first I gave it four stars. But now I give it five because it is quality and works perfect.Do not order this one if you have Doug Thorley long tube headers. It will not reach.

Bought for a 2005 Pathfinder
Bought as a bank 1, o2 sensor 2 replacement. Fits as it should. One thing though, the bung on the exhaust is pointed straight up, so it would make sense that the o2 sensor would not have the wiring run straight out the back as it just runs into the floor above the exhaust. But is does fit, albeit just barely, and does its job.

Did not resolve my CEL issue.
Nothing but issues with this O2 sensor. Should of known when it arrived in a generic plastic bag advertised as a genuine BOSCH sensor. CEL kept coming back on and decided to just go with an OEM Denso one from RockAuto and have had zero issues for months. Just spend the extra money and go with a reputable seller and DENSO brand. I'm trying to get a refund from the seller.

Great alternative to OEM!
Fitment was perfect, although it was a bit confused as it looked different to the poem denso sensor I was replacing, but it has been running great in addition to my new catalytic converter to rid the engine light. Installation was easy as cake, just make sure not to connect it until after snuggling it down. Great value for money as it was a significant price saving compared to denso. Engine light has stayed off since Installation, time will tell for the durability.

コネクター無しも出たよ
PosiLockコネクターは使い回せました。最近、コネクター無しの商品が安く出ているのでコネクター付きを一つ買えば、将来、安くて楽に交換できるようになります。ちなみに1年で壊れました。HCR32で使用。
