Review: Recomendado - Funciona correctamente recomendable Review: Nice sensor - Comes with thread treatment already applied for ready to go installation. - Perfect fit for the firewall side Cat O2 sensor. Existing sensors are 0.8v and this one is 0.72v Not sure it that matters, or if they generally fail upwards as they age. Computer is happy and check engine light is off. Make sure you get the 22mm O2 wrench which is a necessity and a snipe to extend your breaker bar to about 2.5 feet. Removal was while the car was lifted on the front passenger side to the maximum of the jack and then supported. That gives you the best angle to crawl under there head first if you are right-handed. The upper sensor would be a bit trickier and perhaps better to do from the top. Either way, if you have to do one of the firewall sensors you are doing all the hard work and should probably do all 4 on a higher mileage car. The front ones are easy. ## Features - Industry Leading OEM and Aftermarket Oxygen Sensor ( O2 Sensor ) Program - O2 Sensor is Manufactured to meet and exceed OE specifications, increase fuel efficiency , decrease emissions, and improve engine performance - Direct OE Fit , Form , Function - Backed by Walker Products buyer protection for worry free installation and performance - Engineered and Assembled in USA.Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01IAFTUDO | | Brand | Walker Products | | Brand Name | Walker Products | | Customer Reviews | 4.4 out of 5 stars 643 Reviews | | Global Trade Identification Number | 00724620088636 | | Included Components | Sensor | | Item Dimensions | 5.6 x 5.1 x 15 centimeters | | Item Type Name | Oxygen Sensor | | Item Weight | 0.24 Pounds | | Item dimensions L x W x H | 5.6 x 5.1 x 15 centimeters | | Item weight | 0.24 Pounds | | Manufacturer | Walker Products | | Material | Ceramic | | Material Type | Ceramic | | Model | d3775db1-553a-4d86-bead-87d41609fa6c | | Mounting Type | Flange Mount | | Mounting type | Flange Mount | | Output Type | Electrical Signal | | Part Number | 350-34039 | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | Oxygen Sensor | | Style | O2 Sensor | | Style Name | O2 Sensor | | UPC | 724620088636 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Walker Products - **Item dimensions L x W x H:** 5.6 x 5.1 x 15 centimeters - **Item weight:** 109 g - **Material:** Ceramic - **Style:** O2 Sensor ## Images ![Walker Products 350-34039 Oxygen Sensor, Original Equipment Replacement O2 Sensor, - Image 1](https://m.media-amazon.com/images/I/51iuSO75VCL.jpg) ## Questions & Answers **Q: Does it fit in a Jeep liberty 2004 upstream and downstream?** A: I have this products istaled in my 2012 Jeep liberty but you need to purchase the right part for your car. **Q: Is this sensor also for downstream on driver side? 2017 Ram 1500** A: Hello: No, 350-34039 does not fit the Upstream and Downstream positions. 2017 Ram 1500 has 2 gasoline/flex engines that have O2 sensors 3.6L & 5.7L.
