If you're just like me you're tired of being overcharged every time you need to have repairs done to your car! Recently my O2 sensor for my 2014 Chevy Suburban engine light went off! Therefore I obviously needed to have the O2 sensor replaced! I checked with the dealership just to see how much the replacement O2 sensor would cost and they were literally three times the price of the one I found on Amazon which is basically the exact same replica!This Upstream O2 sensor is the O2 sensor that is before the catalytic converter! It is exactly like the original Factory O2 sensor and fits perfectly into my 2014 Chevy Suburban! So far it works perfectly and there have been no issues whatsoever with the new O2 sensor! If there was an issue obviously the engine light would go off! My recommendation is to get this third party Upstream O2 sensor from Amazon instead of getting ripped off at the dealership!I am rating this product five stars because it's a great Upstream O2 sensor for my 2000 Chevy Suburban, it works perfectly, it's 1/3 the price of the dealership and it's super easy to install!
