If you are installing long tube headers or an aftermarket mid pipe on your 1987-2010 Mustang, these O2 oxygen sensor extensions will most likely be needed. When installing full-length headers or a new mid pipe, the factory oxygen sensor might not reach the factory plug, leaving you with a Check Engine Light(CEL). These 18" BBK O2 extensions fix the issue by plugging into your existing wiring plug and your O2 sensor wiring to complete the connection. Features factory connections for a quick and easy installation. This prevents you from having to make any splices or cuts in your factory wiring. Will work on 3 or 4 wire applications.
Some connectors may require the small directional location tabs to be removed on the ends of the connectors to click into place.
