When installing longtube headers on your 4th Gen Camaro or Firebird, the upstream O₂ sensors need to be relocated further downstream. Speed Engineering's 24" black square O₂ sensor extensions make that relocation simple — plug-and-play extensions that allow the O₂ sensors to be moved to the correct position without cutting or splicing any wiring.
Sold as a pair.
⚠️ Important: Some 1993–1997 LT1 F-Body models use a square O₂ connector and some use a flat version. Verify your connector type before ordering.
Features:
- 24" Length — Provides sufficient reach for upstream O₂ sensor relocation with longtube header installations
- Black Square Connector Design — Direct plug-and-play fit for LS1 and compatible LT1 applications
- Sold as a Pair — Both extensions included, one per bank
- No Cutting or Splicing Required — Direct connector fit for easy installation

FAQ
Why do I need O₂ sensor extensions when installing longtube headers?
Longtube headers move the upstream O₂ sensor bungs further back from the cylinder head compared to factory manifolds. Without extensions, the factory O₂ sensor wiring is too short to reach the new bung location. These 24" extensions bridge that gap without any cutting or splicing.
How many extensions are included?
These are sold as a pair — one extension per bank, two total per set.
Will these fit my 1993–1997 Camaro or Firebird?
Some 1993–1997 LT1 F-Body models use a square O₂ connector and will work with these extensions. However some use a flat connector version and will require a different extension. Verify your connector type before ordering.
What connector type do these extensions use?
These use a black square connector design for direct plug-and-play fitment on LS1 and compatible LT1 applications.
Are these compatible with all 1998–2002 Camaro and Firebird models?
Yes. All 1998–2002 Camaro and Firebird/Trans Am LS1 models are confirmed compatible with these square O₂ extensions.
