The sensor’s metal housing and threaded mounting type (18 mm diameter) allow for straightforward installation using a 22 mm hex socket. With a total length of approximately 22.2 inches from sealing surface to connector end, it fits precisely in the designated exhaust system locations of Hyundai Elantra and Kia Spectra vehicles.

Common Applications and Issues Addressed

• Restores accurate air-fuel ratio readings for improved engine efficiency
• Helps resolve check engine light triggers related to oxygen sensor faults
• Reduces emissions by ensuring proper catalytic converter function
• Improves fuel economy by providing precise sensor data to the ECU
• Eliminates rough idling or poor acceleration caused by faulty sensors

Installation Notes and Tips

Installation requires a 22 mm oxygen sensor socket for proper removal and tightening. Ensure the wiring harness is routed away from hot exhaust components to prevent damage. The sensor is a specific fit for Hyundai Elantra and Kia Spectra models, so verify vehicle compatibility before installation. No mounting bracket or additional accessories are included, as the sensor mounts directly via its threaded design.
