The Skunk2 O2 Sensor Extension is designed specifically for the 2006–2015 Honda Civic Si, making it an essential component when installing an aftermarket header. Factory O2 sensor wires are often too short to reach the relocated bung, and this extension provides the proper length while maintaining OEM-like fit and function.
Engineered for reliability, the Skunk2 O2 Sensor Extension is designed to work seamlessly with Skunk2 headers and exhaust systems, ensuring easy installation and secure connections.
