See Fitment Guide below.

Original O2 sensors can fail for various reasons including oil burning, carbon, contamination, or when a sensor reaches the end of it's service life, which can be between 60k-100k miles. While the only true method to find out if an O2 sensor is failing is by checking the onboard diagnostic codes, some signs of a faulty sensor may include:

  • Check engine light triggered by a trouble code.
  • Decreased gas mileage and performance
  • Rough running that doesn't improve after changing spark plugs and plug wires
  • Fouled spark plugs and an engine that runs rich (black smoke, carbon around the tailpipe), which often means the O2 sensors could also be carbon fouled.

It is not recommended to clean any sensors that have been fouled. When in doubt, always replace sensors that have triggered a trouble code or that begin showing signs of wear. Faulty sensors can often be the result of other mechanical issues. *

Note: Some models require different sensors on front and back head pipes. O2 sensors are sold each. Please verify correct fitment using the part number in your factory service manual, returns or exchanges are not accepted on electrical or sensor items.
