Designed for direct-fit installation with OE connectors and anti-seize coated threads, it supports a wide range of Ford and Lincoln models, helping optimize engine efficiency, reduce emissions, and extend sensor life. ## Description 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 performance that you can count on. Bosch 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 damage from exhaust emissions - ensuring a longer sensor service life. Fast-acting heater optimizes sensor operation on Planar and 3, 4, and 5 wire Thimble type sensors 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: Great Product - Installed on 2014 F150. Bosch makes great products. Installed electrical products on multiple vehicles brands and models. My go to electrical component manufacturer. No issues yet. Review: AEM replacement - To those who are looking for an AEM wideband replacement, this review is for you! This is the exact fit replacement for your failed AEM sensor. The harness is shorter than what came with your wideband, but it is the exact replacement for my X series 30-0300. Works perfectly and is able to be read by my gauge and ECU with no errors. Stock up on a few before prices go up and never have to worry 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 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 damage from exhaust emissions - ensuring longer sensor service life - [FAST ACTING HEATER] - Fast-acting heater optimizes sensor operation on Planar and 3, 4, and 5 wire Thimble type sensors allowing the oxygen sensor to reach its operating temperature quicker - within seconds - for optimum performance - [READY TO INSTALL] - 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 easy - Compatible with select vehicles (Note: engine may affect fitment - verify specific fitment details, including sensor position, with fit checker above): FORD: 2011-17 Expedition, 2013-19 Explorer, 2011-14 E-150, 2011-14 E-250, 2011-16 E-350 Super Duty - Compatible with (continued): FORD: 2011-16 E-450 Super Duty, 2013-19 Flex, 2012-14 Focus, 2011-16 F-150, 2011-16 F-250 Super Duty, 2011-16 F-350 Super Duty, 2013-16 F-450 Super Duty, 2012-15 F53, 2013-16 F-550 Super Duty, 2012-15 F59 - Compatible with (continued): FORD: 2011-14 Mustang, 2013-19 Police Interceptor Sedan, 2014-19 Police Interceptor Utility, 2013-19 Taurus, 2015-19 Transit-150, 2015-19 Ford Transit-250, 2015-19 Ford Transit-350, 2015-19 Ford Transit-350 HD - Compatible with (continued): LINCOLN: 2015-16 MKC, 2013-16 MKS, 2013-19 MKT, 2011-17 Navigator ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00EZQIOUI | | Best Sellers Rank | #24,297 in Automotive ( See Top 100 in Automotive ) #15 in Automotive Replacement Oxygen Sensors | | Brand | Bosch | | Brand Name | Bosch | | Customer Reviews | 4.4 out of 5 stars 635 Reviews | | Global Trade Identification Number | 00077212004096 | | Included Components | Oxygen Sensor | | Item Dimensions | 2.2 x 1.97 x 5.83 inches | | Item Type Name | Oxygen Sensor | | Item Weight | 4.64 ounces | | Item dimensions L x W x H | 2.2 x 1.97 x 5.83 inches | | Manufacturer | Bosch | | Material | Stainless Steel | | Material Type | Stainless Steel | | Maximum Supply Voltage | 5 volts | | Measurement Accuracy | High | | Measuring Range | Air-fuel ratio | | Model | 0258017321 | | Mounting Type | Threaded | | Number of Items | 1 | | Output Type | Analog | | Part Number | 17321 | | Specific Uses For Product | Temperature | | Style | Oxygen Sensor | | Style Name | Oxygen Sensor | | UPC | 077212004096 | | Unit Count | 1 Count | | Upper Temperature Rating | 1200 °F | ## Product Details - **Brand:** Bosch - **Item Weight:** 0.29 Pounds - **Item dimensions L x W x H:** 2.2 x 1.97 x 5.83 inches - **Material:** Stainless Steel - **Style:** Oxygen Sensor ## Images ![17321 Premium Original Equipment Oxygen Sensor - Single - Image 1](https://m.media-amazon.com/images/I/51tE1HnaIaL.jpg) ![17321 Premium Original Equipment Oxygen Sensor - Single - Image 2](https://m.media-amazon.com/images/I/51joNzYd9wL.jpg) ![17321 Premium Original Equipment Oxygen Sensor - Single - Image 3](https://m.media-amazon.com/images/I/61zQ5UkVNuL.jpg) ![17321 Premium Original Equipment Oxygen Sensor - Single - Image 4](https://m.media-amazon.com/images/I/51GeTgw0yOL.jpg) ## Questions & Answers **Q: I Would like to make shure, is this for a 2014 f-150 platinum?** A: Yes it will fit.
