Product Details

If your engine is tossing you a oxygen sensor check engine light, replace it with this unit. The O2 sensor measures the amount of unburned fuel in the exhaust pipe to adjust fuel mapping for less emissions and better fuel economy.

When malfunctioning, your MPG and performance can suffer. Replaced fairly easily, you can restore your performance and mileage quickly. Put some anti seize on the threads to prevent it from becoming a permanent part of the exhaust.

Regularly scheduled maintenance as these tend to fail slowly.
