Ntk oxygen sensors are the largest o2 sensor company in the world , they are made by NGK spark plug company and are used in virtually all new japanese cars from the factory. I've installed a lot of them and they are at least equal to if not better than the bosch ones...I wouldn't hesitate to use one.
