When installing long tube headers on modern fuel-injected engines, the O2 sensor bungs are often positioned further downstream than factory locations. This extension kit provides the additional wiring length needed to connect your factory O2 sensors without splicing or compromising the integrity of your vehicle's emissions monitoring system. Essential for maintaining proper engine management and avoiding diagnostic trouble codes.
