Sensitive Sensor. Improve your Sierra's emissions and performance with this replacement oxygen sensor from NTK. Oxygen sensors are critical to your engine's performance. The O2 sensor lets the engine control module (ECM) know how well the combustion process is working. Improve your ECM's ability to determine the proper fuel-air ratio with this upgraded sensor from NTK. Slight differences in sensitivity can have great impacts on performance and emissions output. Oxygen sensors have a definite lifespan, so it might be time to change out your sensor with a sharp new one from NTK.

OEM Compatible. This NTK sensor meets or exceeds all OEM standards. That means it installs and connects just like a factory part. This sensor is for the front (pre-catalytic) position. It includes waterproof OEM-style connectors. NTK warrants this part against failure for 60 days after delivery.

Simple Install. Installation is relatively simple, and should require only basic tools. Consult your service manual for explicit instructions.

Application. This front oxygen sensor from NTK fits your 2007 GMC Sierra equipped with the 5.3L or 6.0L V8 engine.
