The Kooks O2 extension kit for 2014–2019 Chevrolet Corvette C7 includes one 16" rear 4-pin harness and one 21" rear 4-pin harness as replacement extensions for header installations. These harnesses match the extensions included in Kooks header kits where needed and are intended to restore proper oxygen sensor routing when aftermarket headers or exhaust components require added length.
