This Universal Exhaust 4 Wire Lambda Sensor Kit M18 x 1.5MM comes complete with a waterproof connector. It is recommended to replace a lambda sensor around 93,000 miles of driving. A sensor's life is dramatically shortened due to anomalies from the engine, exhaust leaks, poor oil usage etc.
These aftermarket sensors are designed to replace your original equipment part. Universal sensors will need wires cutting to length and may require the use of your original sensor connector; this can be spliced onto the new sensor wiring with minimal equipment and ability. It would be best if you kept the cable length the same as the original.
