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 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.

Installed and the check-engine light went away. Bank 1 Sensor 1 on the Explorer Sport is under the engine near the oil pan. It took about 2 hours to replace and I have been doing work on my cars all my life. Lifted the vehicle, removed the front passenger side tire and was able to access the sensor. What gave me the most trouble was the darn connector. You have to disconnect and connect using one hand.

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.

Fixed my check engine light, still off after 500 miles. Exact fit. Install wasn’t too bad, just use a big 7/8 wrench.
