Description
Wideband air/fuel ratio sensors utilize a sophisticated sensing element that enables them to measure the amount of oxygen in the exhaust rather than switching between rich and lean responses. True direct-fit OE connectors and harness for easy installation. Pre-coated threads with anti-seize compound right out of the box. Robust sensor design increases sensor longevity. Seared protection tube due to 100% functional quality test.
