02 Sensor Extension Harness for installing long tube headers. These are plug-and-play extensions and do not require any cutting or splicing! Some manufacturers long tube headers require the use of these 18″ extensions to give the factory 02 sensor harness enough length to reach the new 02 sensor location. Feel free to call us if you have any questions on which headers will require extensions.

*PRICE IS PER EXTENSION – 2 REQUIRED*
