    That same commitment was the driving force in the development of additional product lines such as NTK Oxygen Sensors, NTK Knock Sensors, and a variety of other sensors. Constantly developing and researching, the company also resulted in a series of world firsts for the industry, including but not limited to copper core spark plugs, iridium spark plugs, and “V-Groove” spark plugs that proved to be ideal for clean-burning, lower-emission engines.

    I replaced both the the upstream and downstream oxygen sensors. This product looks just like the OE product. It is a high quality made product and I am very happy so far with its performance.
