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

Frequently Asked Questions:
Q: 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.
Q: How many extensions are included? These are sold as a pair — one extension per bank, two total per set.
Q: 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.
Q: 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.
Q: 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.
