Description
"Plug and play". When your modify your exhaust system, sometimes the stock O2 sensor harness just comes up too short to connect the O2 sensors, but this SR Performance harness extension kit will help bridge the gap.

Great for modified exhaust systems. If your stock wiring harness is too short to connect your existing O2 sensors to a new set of headers or a mid pipe, don't just leave the old wires dangling - because your car just won't pass inspection. Instead use a set of 18" O2 Sensor Extensions to make the connection a snap.

Features:
  • Sold as a set of two.
  • Kit includes two harnesses extensions, measuring 18" each.
  • For all 86 - 09 exhaust system configurations.
  • O2 sensors NOT included.
  • Intended for use to extend to upstream O2 sensors; however, can be used upstream or downstream if needed.

Note: Removal of directional tabs on connector ends may be required for proper fitment on some applications.

Review & Install Video

So you just installed a new set of long tube headers or an aftermarket midpipe, and now your factory O2 sensor harness is a little too short. If that sounds like you, this O2 sensor extension kit is your solution. This kit for your ’86-’09 Mustang includes two harnesses that extend both your primary and secondary O2 sensor wires by 18 inches. That should be enough to bridge the gap between your factory O2 sensors and your factory harness. The great thing about this kit is that it’s completely plug and play, so there’s no need to hack up your factory harness in order to extend your wires. It’s a very straightforward install that should take you no more than a few minutes. If you’re pumped to install that new off-road x-pipe, or that new set of headers, only to find that your O2 sensors no longer fit, this kit will solve that problem easily without breaking the bank.

Hi, Would this O2 Sensor Extension kit work on a Mustang Bassani Catalytic X-Pipe for Automatic Stainless (99-04)? Or does American muscle have other O2 Sensors that would be better fitted for that Bassani Catted X-Pipe? Thank you.

    They Work

    I installed these with my new O2 sensors on an 04 GT and haven't had any issues with them at all. I only needed the drivers side with my UPR catted x and it plugged right into the sensor after trimming the little plastic "studs" on the sensor. Pretty simple install and easy to zip tie to the chassis and get out of the way.

    Excellent perfect fit

    Used on my 1992 f150. Put on new headers and exhaust and needed extra length to reach original plug. Just what the doctor ordered.

    Needs a "how these work" instructional sheet.

    These really need a set of instructions instructions outlining how these work exactly to ensure correct installation.

    Only works after alteration

    The keys on the plug and receptacle do not line up with the corresponding plugs from the car. You have to cut off the little plastic keys in order to make it fit. It's not hard to do, but it may catch you off guard if you are not anticipating it. After you cut them off the pins line up just fine, and the clip still holds the plug together. So it does work.

    O2 sensor ext.

    Nice. Fits perfectly, but the passanger side extension was to long, so I had to tie part of the wire to the underbody.

    O2 Sensor Extenders

    I needed these after installing my MAC long tube headers, these extenders in addition to the longer wires on the NTK O2 sensors give you PLENTY of wire to work with, just what I needed. Everything plugged together with no problems and I tucked the extra wire out of the way with some zip ties.

    o2 Extensions for Headers

    The two ends and slot on each sensor extension were the same asymetrical. The two ends and slots on the o2 sensors that plug into the header are symterical. I guess ill have to grind of part of the sensor or exension to make it fit...
