Review & Installation Video

Review & Install Video

Plug and Play. When installing a set of long tube headers on your GT or V6, you may notice the factory oxygen wire harnesses are short and won't the front (upstream) o2 sensors. The perfect solution to fix that issue is the O2 Wire Harness Extension Kit from BBK Performance. These 12 inch long harnesses feature OEM factory connectors that will provide an easy plug and play install to bridge the gap and allow you to reconnect your sensors. If you don't reconnect your sensors, your engine's computer will not be able to monitor if your fuel mixture is burning rich or lean.

Application. This set of two 12 inch BBK Performance O2 Sensor Extensions are designed to extend the front (upstream) O2 sensor harnesses on the 2015 to 2017 GT and V6 Mustangs.

Please Note. O2 Sensors are not included with these extensions.

Bought this because the factory length O2 sensors didn't reach for the XForce Headerback system, these extended it perfectly.

Fit ecoboost?

AustinP

  • Due to the position of the downpipe instead of having headers on the naturally aspirated motors, the O2 extensions are not intended for use on a Ecoboost Mustang.

These are labeled as a front pair, but I already have a pair installed on my front sensors, and they work fine. My question is would they work to extend my back sensors as well?

Devin

  • The BBK O2 Wire Harness Extension Kit would only work for the Front, as the connectors will be different between the front and rear O2 sensors.

I have the 2015 Mustang GT. It's stock, but I'd like to add the Borla ATAK exhaust. Will I still need this extension?

    BBK O2 Extension Kit

    If you need to extend the front O2 sensor cables after replacing the stock exhaust headers this extension kit is the one to buy. Excellent workmanship and easy to install.

    Needed for Long Tubes

    Don't forget these if you're doing long tubes. For the X force kit, you'll only need the passenger side.

    Bbk O2 sensor extensions

    I was told that these were needed for the ford racing cat back exhaust, after taking my car to the dealer for the install I was informed that they were not need because I wasn't installing headers or relocating the O2 sensors. So far I have no engine lights or warnings and the car seems fine without them, I just wish that I hadn't spent 50 bucks that I didn't have to.
