BOSCH 13371 Premium OE Fitment Oxygen Sensor - Compatible with Select Acura EL; Honda Civic, CR-V, Element

Cured the proplem.Off with the check engine light

👍 great!

2008 BMW 335i with the N54 engine, bought this to clear a 2C7B code (secondary oxygen sensor fault). The splice kit is really nice, it takes about 30 minutes to splice into the BMW connector, at a much lower cost! I put about 300 miles on the car since i did this repair and the code hasn't came back.

This will be the third of these sensors in the car. The original sensor and installation include a model-specific connector, and the need to pass that connector through a grommet in the tub. The grommet sits in an, um, interesting position that normally demands lowering the exhaust to access. Using this 15735 sensor allows me to pass another wire from inside the cabin, and use it to "snake" the cable from the sensor back inside, where it's very convenient to splice the new sensor cable to the original via a more common connector. It also saves some $$ along the way vs. buying the specific sensor from Porsche. I my 25-plus years with the car, these sensors have worked perfectly. The improvement in fuel economy alone pays for a new sensor in well under 50K miles. Doing the same math with the Porsche-supplied sensor more than doubles the payback period, effectively costing more than just the difference in sensor price. If you are comfortable managing the new connector install, there's a significant economic benefit in using this sensor. I've been religious in keeping the car to original spec all its life; I'm fairly sure no concours judge will ding me points for an extra connector in the sensor cable. Hasn't happened yet anyway. Buy this one and save money. Simple as that.

It arrived on time, was packaged well, and installed without any issues. The sensor is an OEM replacement, so I know it’s reliable and built to last. After replacing the old sensor, my vehicle’s performance has improved.

I love the product... Genuine Bosch for a fraction of the cost of the Genuine Bosch that has Bosch numbers on one side and a three pointed star on the other. I bruised the heck out of my hand reaching the sensor and getting it out and reinstalled as it is a very tight fit between the firewall and cylinder head. But, the savings over taking the car to the dealer was huge as it would have been $500 with them. Be sure to have your E8 star socket, long extensions and U joint extension. Once installed and torqued properly to 8 N-m (per the Benz service DVD) I cleared the code and the car is running great with no more long crank times to start and no more check engine light. The product is great, but I have a couple gripes about Amazon on this...1) I ordered relatively early on a Sunday and paying $3.99 extra for over night shipping was not offered as it usually is with Prime. Instead, all that was offered was my "Free Two Day" shipping which didn't have the item delivered until Wednesday. So, my car had to sit for 3 1/2 days waiting for "Two Day" shipping. With Prime it is odd how sometimes Sunday counts and sometimes it does not. And, 2) The Amazon fit list is incorrect. Amazon says that this items does not fit my 2005 E500 4Matic. In fact, it does fit and is an exact match. I removed the old sensor and found the correct part number based on the actual part. The actual part has a Bosch number on one side and the Benz part number on the other. The Bosch number was 0261210171. By cross referencing that number through Bosch and other parts sites as well as looking up the Benz part number, I was able to verify that indeed ...70 was a proper replacement for ...71. I have no idea where Amazon is getting their fit data, but the fact that all the other sites show it as the right part both as replacement for the part and the right part for the VIN, it is clear Amazon is getting some bad data.

Replacing either of the "upstream" heated o2 sensors (= lambda sensors) looks to be and should be a pretty easy job on most N51 or N52-powered BMW cars. You should remove the plastic engine cover and the whole cabin air filter/cowl covering, but that's about all it takes to get access to the rear bank o2 sensor that sits just below a little metal shelf/cover of sorts. The wiring for both sensors wraps around back of the valve cover and joins two connectors on top of it. I spent way too much time trying to remove that little metal cover just above the bank 2 o2 sensor because of a tiny rusted bolt (E8 Torx) caused by 17+ years of heat and exposure. Eventually I just bent the cover upward enough to allow an offset-style o2 sensor socket to slip past it with the cable in it and I was able to unscrew the bad upstream o2 sensor easily. With the little cover out of the way, the whole job should take you less than an hour to replace one, or maybe even both of these sensors on the N52 engine. The new sensor has some appropriate anti-seize on its threads already. After you install it/them, reset your diagnostic codes and you're on your way - my last one lasted 150,000 miles.

While this part fits perfectly both mechanically and electrically, it will quickly cause a P0130 (Upstream O2 sensor) error code. I will point out that this was the problem on my 2005 MINI Cooper S. Of course this part is shipped in a sealed bad that says "If this bag is opened, this part cannot be returned.) I was at my wits end trying to resolve this issue. I finally went to the dealer where the tech explained that pretty much only the factory O2 sensor works properly in these vehicles. While I was not happy with the price of the factory sensor, I was happy to finally get a sensor that works properly. In the photos the design of the actual part of the sensor that extends into the exhaust stream is shown. The Bosch sensor is on the right, and the factory sensor is on the left. Obviously I would have given this item zero starts if I could considering the number of hours spent trying to diagnose the problem.

Worked perfectly, allows the flexibility to extend o2 sensor wires to accommodate aftermarket headers and exhaust pipes with different O2 sensor locations than stock. Takes a bit of technical skill to install the supplied splice but nothing major.

Installer sur 323i 2007 très bonne qualité ajustement parfait sans problème très satisfait je recommande

Installed perfectly. Working as it should. Very satisfied .

Montato ,anomalia sparita 👍

Perfect fit
