Plug-and-Play O2 Extension Harnesses

Kooks Oxygen Sensor Extension Harnesses are a must when upgrading to long tube headers or when creating a custom-style exhaust system. These extension harnesses help avoid the need for any cutting, splicing or soldering of the factory O2 sensor wires. Each harness is a simple plug-and-play right into the OE-connection for a hassle-free installation.
