    Regains Lost Power. A Kooks Oxygen Sensor Extension Harness will help you regain consistent superior performance. This is crucial because a bad oxygen extension harness may result in lousy fuel economy and poor performance and your vehicle may fail the emissions testing. A durable O2 extension harness will replace your worn-out stock harnesses and give you the power that your Mustang needs.

    Superior Assembly. The Kooks O2 Sensor Extension Harness ensures a perfect fit for your stock oxygen sensor. It is crafted from premium-quality stainless steel material and unmatched craftsmanship to ensure that it's a high-quality direct replacement for your failed or worn-out OEM oxygen sensor extension harnesses.

    Simple Installation. These Kooks O2 Sensor Extension Harnesses feature OEM stock connectors that offer an easy and simple plug-and-play installation. With basic mechanical expertise, you can easily bridge the gap between the long tube headers and your O2 sensors using simple and readily available household tools.

    Warranty. The Kooks O2 Sensor Extension Harnesses have a limited lifetime warranty from the manufacturer. This warranty covers against any defects in the manufacturing process and material and structural faults, and it is not transferable.

    Application. Designing of the Kooks O2 Sensor Extension Harness ensures that it's a direct replacement for all Ford Mustang GT500 models released between 2011 and 2014. Sold individually.

            Excellent product

            Fit and finish is excellent as expected from a Kooks product. Only downfall was it was shipped directly from the manufacturer. It was fast but required a signature, would not accept a signed door tag. After multiple attempts I was able to receive them. Still happy with product, disappointed with manufacture policy.
