Replacing or updating the oxygen sensors in your GMC Sierra with aftermarket 2014-2017 O2 sensors ensures that you won’t run into emission problems – and that your ECU will get the correct signals to deliver a high powered air-fuel mixture to the engine. Some of these sensors offered by AmericanTrucks come straight from NGK, the company that developed today’s advanced yet affordable oxygen sensors with their 1990 invention of high temperature cofired ceramic elements that offered higher accuracy and lower cost than the earlier types. You can find both front (upstream) and rear (downstream) oxygen sensors among the O2 sensors on our site, so that you can change out either or both depending on what your truck needs. Equip your Sierra with the best and ensure that the most effective blend of air and gasoline is delivered to its combustion chamber!
