A branch of the Japanese NGK spark plug company, NTK is a supplier of premium quality 2007-2017 exhaust components – specifically, oxygen sensors – that can be used in your Sierra pickup. NTK uses proprietary technical ceramics in the manufacture of their oxygen sensor’s sensing element, which provides exceptional levels of accuracy and sensitivity in measurement. These 2007-2013 exhaust accessories are precision made to ensure a great fit and correct functionality. A factory fitted OE connection is included so that it’s easy to install NTK’s 2014-2017 exhaust accessories directly in your pickup. Thoroughly tested throughout the production process, the oxygen sensors improve your vehicle’s emissions and gives you extra fuel economy at the same time. These NTK sensors are attuned specifically to the Sierra so that they communicate with the ECU and your truck uses just the right air-fuel ratio to get its engine humming with greater efficiency.
