Product Description

The BBK 1676 O2 Sensor Wire Extension Harness Set is a performance-focused wiring upgrade engineered specifically for 1986-2010 Ford Mustang models equipped with 5.0L and 4.6L V8 engines. When installing long tube headers or aftermarket mid-pipes, factory oxygen sensor connectors may no longer reach relocated sensor positions. These extension harnesses provide the extra length needed to maintain proper sensor connection without cutting or splicing factory wiring.

Each harness features OEM-style connectors that plug directly into the vehicle's existing wiring and relocated sensors for an easy and reliable install. The 18-inch length and protective heat-resistant sleeve ensure both flexibility and durability in high-temperature exhaust environments. Ideal for Mustang enthusiasts modifying their exhaust systems, this harness set supports accurate O2 sensor signal transmission and helps prevent check-engine lights due to disconnected sensors after exhaust modifications.
