Overview

The Speed Engineering O2 Extension is a 24-inch extension designed for easy relocation of oxygen sensors. This is particularly useful during the installation of headers that require the oxygen sensor to be moved further downstream.

This pair of O2 extensions is specifically designed for LS2 and LS3 engines. Applications include C6 LS2, LS3, and LS7 Corvettes, as well as LS3/L99/LTT (V6) Camaros, and the 2014-2018 SS Sedan.
