LS1 O2 Oxygen Sensor Extension Harness 24-Inches | Set of 2 | 4-Pin Plug-and-Play Extension | Fits Camaro Firebird Pontiac Chevy LS1 Applications | OEM-Style Connector Design

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.

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".

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

This has single alignment slots! Hard to tell in the picture as it only shows 1 side of each. Did not fit my Chevy Silverado which has 2 alignment slots. Had to modify for it to work. Truck was going to the tuner so I had to make it work.

Worked great I installed long tube headers in my Camaro and used these and still working great

Ordered this to relocate an o2 sensor, fits perfectly on a 2006 TBSS, thanks again Michigan Motorsports!

Just what I needed to finish my exhaust mod

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.
