NTK is the company that makes the O2 Sensors that Chrysler uses for there 2003 Dodge Ram Hemi. All others I dont know. Could be Bosch, I dont know. But i do know that my 2003 Ram Hemi did not like Bosch O2 sensors!!!! I put a Chrysler factory NTK O2 Sensor and all my problems went away. And havent been back for over 2 years!!!! Knock On Wood!!!!
