The Skunk2 Alpha Series O2 sensor wire harness extension provides plug-and-play length for 2006–2014 Honda Civic Si models when relocating O2 bungs for aftermarket headers and exhaust. Designed for use with Skunk2 headers and exhaust, the extension solves reach issues where OEM sensor wires are too short to access new bung locations, simplifying installation of performance exhaust components.
