Your cart is empty.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.

Cleared the code on it's own after about ten miles of driving, don't waste your money on cheaper sensors, ten or fifteen bucks is not worth the aggravation of changing a sensor twice.

I installed this on my 2003 Pontiac Grand Am Gt, it was hard to install, just because of the placement in the Pontiac. It’s not the products fault lol. My engine codes went away after installation which is great. The build quality is just like the old one. Sensor quality seems good so far. I just installed but I can tell my mpg is up a bit after installation.

I ordered two upstream sensors to replace the two original on my 2010 ford explorer with 224000 miles. one of the two immediately threw a heater circuit code. I pulled it back out and the heater circuit showed an open line. I put one of the old ones back in and it worked fine. Amazon did replace this and the replacement was good. I also had ordered a Bosch upstream for another vehicle I tested the heater circuit in it before installing it was bad also.

This fit perfect! My truck is a Canada built truck so I needed the special plug and this one was it. I thought it was going to be expensive but it was a great price! Super easy to install, the hard part was getting the old sensor out! My check engine light is now out and the code is cleared, problem solved!

Purchased these for LM7 engine swap. Unfortunately the ECM was American and required case grounded o2 sensors. These are ECM grounded o2 sensors. Didn't work.. Not the manufacturers fault.

I bought it used. Put it in and it works like a charm. Thought i'd give a used item a chance. When I opened it looked just like it was brand new. So far so good!
