Your cart is empty.24" 02 Oxygen Sensor Extension Harness Oxygen sensor extension cable for GM LS1 engines including the 1998-2002 Camaro Z28/SS, Firebird Trans-Am with the LS1 engine. When you install most aftermarket headers, it moves the oxygen sensor bungs towards the rear of the car, farther from the factory harness, so extensions are required. These extensions make the installation hassle free by not having to cut and splice the factory wiring. It also makes removing aftermarket headers much easier. This is the Black Square 4-pin plug. It is different than the Gray Square 4-pin. These oxygen sensor extensions will make for an easy installation and will avoid the problems of faulty O2 sensor readings that are common with cutting and splicing. These are a must for any long tube header installation!

I don’t drive it daily but I don’t have any oxygen sensor codes. Seemed like good quality.

Although longer than needed, these are answering the mail to my need.

I needed these for my 98 Camaro Z28 after I installed my new headers. I tried a 6 inch extender but it wasn't long enough. These worked just fine.

I needed an extension for the passenger side O2 sensor on my 2008 Trailblazer SS...this fits great and is long enough to zip tie away from any heat or vibration.

I purchased a new oxygen sensor because I had a code for a bad sensor, and to clean things up I bought these extensions because I have headers. Long story short after a month of going on a wild goose chase I found two wires not in the correct spot in the connector on each end. Talked about pist off. I couldn’t drive my car for over a month

Quality is nice, it did not fit my square style of connector with out some mods. The mods were easy to make, which if you do make these mods instead of returning, you will be happy with this product.

Fit perfectly on my 2008 TBSS. Even though these say they fit an LS1, these worked on my LS2 motor. The black plugs and keyway tabs inside matched perfectly with the black connectors on my O2 sensors. Everything looks and feels well made. Only gripe is I wish these came in shorter lengths, only needed 6".

Not their fault this did not fit my vehicle was hoping it would work for my Pontiac G8 it did not. Very similar except for the oem 02 inside has a small little tab on both sides this has one. Ended up splicing and using the extra wiring.
