FAQ
Why do I need O₂ sensor extensions for these vehicles?
The full kit longtube header listings for the 6th Gen Camaro and Gen 3 CTS-V include O₂ extension harnesses, but if you purchased headers only, these 12" extensions provide the plug-and-play relocation needed for the rear downstream oxygen sensors.
How many extensions are included?
This kit is sold in pairs — two 12" O₂ extensions, one for each bank.
Is installation plug-and-play?
Yes. These extensions connect directly to your factory O₂ sensor harness connectors.
What engines are these extensions compatible with?
These extensions are compatible with the 6.2L LT1 found in the 2016+ Camaro SS and the 6.2L LT4 found in the 2017+ Camaro ZL1 and 2016–2019 CTS-V.
Will these work on a 2022–2023 CT5-V Blackwing?
This listing does not list the CT5-V Blackwing in its applications. If you're installing Speed Engineering longtube headers on a CT5-V Blackwing, contact Speed Engineering to confirm the correct O₂ extension part for that application.
