Best Oxygen Sensors of 2026

"I hooked these up and my codes disappeared. I was able to pass my yearly inspection for tags, and the price was way better than local stores."

"The product was delivered quickly and worked exactly as described. Installation was a breeze. I would definitely recommend this seller."

"I bought these sensors for my 2004 Sport Trac and the check engine light turned off after installation. I recommend disconnecting the battery before installing to help the computer recognize the new sensors."

"I was really impressed with the super quick delivery—my order arrived the very next day! The price was unbeatable and it cleared my O2 sensor codes on my 2019 Cherokee 3.2 right away. For anyone struggling with similar sensor issues, this is definitely a highly recommended lifesaver."

"Although these O2 sensors appear well-made, my 2003 Jeep Grand Cherokee Laredo 4.0 wouldn’t accept them, which made passing emissions a real struggle. I’m not sure why, but I just can’t get them to work for my vehicle."

"Even though it’s listed as a fit for my car, the sensor glitched after installation—sometimes it worked, but then it would stick and trigger check engine codes like P0175 and P0135. I missed the return window, so unfortunately I’m out $40 and still looking for a reliable solution."

"I was impressed by how simple these sensors were to install on my Ford. The wire length was perfect, and after replacing the old ones, my engine light turned off and the car ran smoother than before. They’re definitely worth the money."

"This is my second purchase of this set because they fit perfectly and are a breeze to put in. Both times, the check engine light issue was resolved right away. The value for the price and quality is outstanding."

"Although the product seemed fine, I ran into trouble codes and my car stalled after installing these. They’re supposed to work for upstream and downstream, but in my case, that wasn’t true. I’ll be switching to OEM parts, even though it costs more."

"I’ve installed this on a 2014 F150 and several other vehicles. Bosch is my go-to brand for electrical components. No problems so far."

"This was a perfect replacement for my kid’s 2012 Ford Focus Titanium. The old O2 sensor was covered in carbon, but this one installed easily and worked flawlessly after clearing the code. I’d recommend it over cheaper alternatives for long-term peace of mind."

"Installed this on my 2016 Explorer and after replacing it, the engine code disappeared. It’s working great so far."

"I've purchased these sensors twice because they're a perfect fit, high quality, and budget-friendly replacement for the original parts. I've had no issues and would definitely recommend them to others."

"This sensor fixed the O2 fault on my 2014 Equinox. Just make sure you have the proper socket tool for the upper sensor installation."

"The sensor fit my Saudi Chevrolet Captiva 2015 2.4L (not sport) perfectly. Everything arrived on time, worked as described, and the installation was smooth. Highly recommended."

"After switching to these OEM sensors, my check engine light finally turned off after nearly a year, and I was able to pass emissions without any trouble. I had tried aftermarket plugs and other parts first, but nothing worked until I went with the genuine sensors."

"I put these front O2 sensors on my 2012 GMC Sierra with 96,000 miles and noticed my fuel mileage improve from 18.2 to 19.9 mpg. I wanted to restore accuracy to the air/fuel ratio readings, and after a few trips, it’s clear the sensors made a positive difference."

"I was hesitant because of reviews mentioning packaging and branding, but after 2,000 kms on my 2013 Suburban, the part worked perfectly and my codes haven’t returned. Previously, cheap sensors gave me issues, but this one fixed everything. Definitely worth choosing OEM quality."

"I replaced my old sensor with this genuine Bosch part, and installation was straightforward. Performance has been flawless, and I’m happy with the fast delivery."

"This sensor was a perfect fit for my 2007 Honda Civic Si Turbo. The readings are accurate and I'm very satisfied with the OEM quality it provides."

"I tried other wideband sensors from Amazon, but only the used Bosch sensor worked properly. The others gave me erratic AFR readings. Going forward, I’ll stick with trusted, original Bosch sensors for critical engine parts."

"I chose this kit because of the excellent price and the peace of mind it offers. Replacing my high-mileage original parts with these has definitely helped my car run more efficiently."

"Installation was simple and these sensors worked immediately on my Dodge Caliber. Unlike my previous purchase elsewhere, I experienced no check engine light problems with these."

"I'm grateful for this part—my car is running great now. I'll definitely return to shop again."

"I got this O2 sensor for my 2014 Jeep Sahara and it cleared both the low voltage and downstream sensor codes right away. With the proper socket, I could access everything easily from underneath without removing the wheel liner. Even if the sensor doesn't last forever, it was enough to pass my state's emissions test."

"The sensor was a perfect fit for the firewall side catalytic converter. The computer accepted it and the check engine light turned off. I recommend getting the 22mm O2 wrench and an extension for leverage; that made the job straightforward. If you're doing one sensor, it's a good idea to replace all four if the car has high mileage."

"I had this part installed and haven't had any problems since. It was a smooth experience overall, and everything is working as expected."

"I installed this oxygen sensor on my 1999 Silverado 1500 and it worked flawlessly. The quality is impressive and it arrived quickly."

"This product is exactly what I needed—right fit, good price, and prompt delivery. I would definitely recommend it to others."
