This Kooks kit provides two 6 inch, 4 pin oxygen sensor extension harnesses that relocate the O2 sensors after fitting longer headers on the 5.7L HEMI, keeping the factory sensors in reach and helping avoid connector strain and check engine codes. Like all Kooks hardware it is handcrafted in the USA to the same quality standard as the company's headers and exhaust systems.
