Bosch Wideband Oxygen sensors are 100% tested for full functionality, resulting in a seared appearance of the protection tube, to ensure every Bosch manufactured sensor meets Bosch's rigorous standards for quality and performance. Exclusive double laser-welded stainless steel body is totally submersible and sealed tight to protect against from exhaust emissions — ensuring a longer sensor service life. Fast-acting heater optimizes sensor operation, allowing the oxygen sensor to reach its operating temperature quicker – within seconds – for optimum performance. True Direct-fit OE connectors and harnesses, along with threads pre-coated with anti-seize compound right out of the box, make installation simple and hassle-free. It’s critical that oxygen sensors are replaced at the suggested intervals provided by vehicle manufacturers before the sensor fails. Following the recommendations will prevent long term damage to a vehicle’s engine, reduce harmful carbon dioxide (CO2) emissions and save money when refueling your vehicle. Review: 100% genuine Bosch sensor, made in Germany, at a great price. - Extremely pleased with this purchase for my 2002 VW Passat 1.8T. It is almost one fifth of the price from my local garage - but is exactly the same product! I was a bit dubious at first, but I searched on the Bosch website for my vehicle model number - and up came this part number. So I was confident that it was the correct part, but thought maybe it was manufactured elsewhere, so perhaps not so good quality? But I was wrong! This is a 100% genuine full-spec Bosch part manufactured in Germany. See the pictures of the packaging I have uploaded. The sensor comes complete with a full installation kit and has the proper connector already fitted. Some other sensors don't include this and you have to fit the connector yourself. It is now installed in my car, and it works perfectly. I wasn't sure if my sensor needed replacing but after replacing half a dozen other components in the vacuum system and still having the MIL light coming on, I thought it worth a try, especially at this amazing price. A couple of tips if you are thinking of buying one. Firstly, do NOT remove the protective cap from the sensor until you intend to install it. It is there to keep the special lubricant in place so you can remove it in the future. Secondly, you must remove the old sensor whilst the exhaust is hot otherwise you can't get it out. Be very careful, protect your arms and hands from burns from the exhaust and engine block. Thirdly you must use a special 22mm oxygen sensor socket spanner, they are about £10 - but its impossible to remove without one. It appears to be a recommendation to replace this (upstream) sensor every 100K miles. My car has only done about 65K but the sensor had been contaminated with a silicon sealer used to seal the rocker gasket. Oxygen sensors do NOT like silicon - mine worked but was slow response, reduced the engine power output and caused lumpy idling. Much better now. Review: Great OEM Replacement for VW - Bought this to replace one of the O2 sensors on my 02 1.8t Passat and it works flawlessly. Plugged in fine, installed just like it should, and has worked great for over 20k miles so far. The little zip ties that come with it are a nice touch, but I didn't use them. Would definitely buy again! ## Features - [INNOVATIVE TECHNOLOGY] - Every Bosch Oxygen Sensor benefits from the technological and manufacturing experience gained from decades of production since first inventing the Oxygen Sensor in the late 1960's, ensuring long-lasting, superior performance - [FACTORY TESTED] - Seared appearance of protection tube is a result of a 100 percent fully functional quality test to ensure every Bosch manufactured sensor meets Bosch's rigorous standards for quality and performance - [STAINLESS STEEL BODY] - Exclusive double laser-welded stainless steel body is totally submersible and sealed tight to protect against contamination from exhaust emissions ? ensuring longer sensor service life - [FAST ACTING HEATER] - Fast-acting heater optimizes sensor operation, allowing the oxygen sensor to reach its operating temperature quicker ? within seconds ? for optimum performance - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00427MIFC | | Best Sellers Rank | 122,286 in Automotive ( See Top 100 in Automotive ) 694 in Car Oxygen Sensors | | Brand | Bosch | | Customer Reviews | 4.7 out of 5 stars 540 Reviews | | Global Trade Identification Number | 00028851173513 | | Included Components | Other Vehicle Parts( AUTO_PART ), Performance Parts - Underhood, Engine Management, automotive-oxygen-sensors | | Item Dimensions | 5.6 x 14.8 x 10 centimetres | | Item Type Name | Oxygen Sensor, Original Equipment (Audi, Bentley, Volkswagen) | | Item Weight | 0.15 Pounds | | Item dimensions L x W x H | 5.6 x 14.8 x 10 centimetres | | Item weight | 0.15 Pounds | | Manufacturer | BOSCH | | Manufacturer Part Number | 17351 | | Material | Ceramic | | Maximum Supply Voltage | 12 Volts (DC) | | Maximum supply voltage | 12 Volts (DC) | | Measurement Accuracy | high | | Measuring Range | A wide range of air-fuel ratios | | Model Number | 17351 | | Mounting Type | Vent | | Output Type | electrical signal | | Specific Uses For Product | Temperature | | Style | Oxygen Sensor | | Style Name | Oxygen Sensor | | UPC | 028851173513 028851940535 826732121376 | | Unit Count | 1.0 count | | Upper Temperature Rating | 800 Degrees Celsius | ## Product Details - **Brand:** Bosch - **Item dimensions L x W x H:** 5.6 x 14.8 x 10 centimetres - **Item weight:** 0.15 Pounds - **Material:** Ceramic - **Style:** Oxygen Sensor ## Images ![Bosch 17351 Original Equipment Wideband Oxygen Sensor - Compatible With Select Audi A4, A8, TT, Quattro; Bentley Continental; Volkswagen Beetle, EuroVan, Golf, Jetta, Passat, Phaeton, Touareg - Image 1](https://m.media-amazon.com/images/I/61SVEGJjvuL.jpg) ![Bosch 17351 Original Equipment Wideband Oxygen Sensor - Compatible With Select Audi A4, A8, TT, Quattro; Bentley Continental; Volkswagen Beetle, EuroVan, Golf, Jetta, Passat, Phaeton, Touareg - Image 2](https://m.media-amazon.com/images/I/61Ru5wh4B0L.jpg) ![Bosch 17351 Original Equipment Wideband Oxygen Sensor - Compatible With Select Audi A4, A8, TT, Quattro; Bentley Continental; Volkswagen Beetle, EuroVan, Golf, Jetta, Passat, Phaeton, Touareg - Image 3](https://m.media-amazon.com/images/I/611kY4q0VQL.jpg) ![Bosch 17351 Original Equipment Wideband Oxygen Sensor - Compatible With Select Audi A4, A8, TT, Quattro; Bentley Continental; Volkswagen Beetle, EuroVan, Golf, Jetta, Passat, Phaeton, Touareg - Image 4](https://m.media-amazon.com/images/I/61sfrBUadTL.jpg) ![Bosch 17351 Original Equipment Wideband Oxygen Sensor - Compatible With Select Audi A4, A8, TT, Quattro; Bentley Continental; Volkswagen Beetle, EuroVan, Golf, Jetta, Passat, Phaeton, Touareg - Image 5](https://m.media-amazon.com/images/I/61HMaidNRJL.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Questions & Answers **Q: Would this work on my 2004 Audi 1.8T quattro?** A: Best way to know is to look up your car at boschautoparts.com.
