Product Description

The Kooks EX685-Z O2 Extension Kit is designed to facilitate the installation of Kooks long tube headers on the 2014-2019 Chevrolet Corvette C7. This kit includes two high-quality extension harnesses - one 16 inches and one 21 inches in length - both equipped with 4-pin connectors to ensure a secure and reliable connection to the vehicle's O2 sensors.

These extension harnesses are essential when installing long tube headers that relocate the O2 sensors further from their original positions. By providing the necessary length, the EX685-Z kit ensures that the O2 sensors can be properly connected, maintaining the vehicle's performance and emissions monitoring capabilities.

Installation is straightforward, utilizing OEM-style connectors for a plug-and-play fit. This kit is a must-have for Corvette enthusiasts looking to upgrade their exhaust system with Kooks headers, ensuring a seamless and efficient installation process.
