BBK 12" O2 sensor extension harnesses are intended for 2005–2024 Dodge front O2 sensor applications where BBK long-tube headers relocate sensor positions. Sold in pairs, these OEM-style extensions use factory connectors for direct plug-in installation without splicing, include a heat protective sleeve for durability, and provide the added length required to reach relocated sensors after header installation.
