It is built with a threaded mounting, a four-wire heated design, and a male connector for simple installation. Confirming vehicle, bank and sensor position plus emissions standard (Federal vs California) before ordering helps avoid incompatibility.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and engine types work with this A-Premium oxygen sensor?\u003c\/h3\u003e\n\u003cp\u003eThis sensor fits a range of Hyundai and Kia models from the early 2010s to late 2010s when the vehicle uses a downstream Bank 1, Sensor 2 arrangement.
