A-Premium O2 Oxygen Sensor Kit 4-Piece for Chevrolet V6 — Heated 4-Wire, 520 mm Leads

A-Premium Upstream & Downstream O2 Oxygen Sensor set is a four-piece heated oxygen sensor kit designed to replace factory sensors on compatible Chevrolet, Buick, GMC, Saturn and Cadillac V6 models.

This A-Premium kit includes four threaded, heated oxygen sensors with male connectors and 520 mm overall lead length, supplied in a boxed package. It’s built to match common OEM form factors and reference numbers, making it a direct-replacement option for a wide range of 3.0L and 3.6L V6 vehicles from model years around 2009–2017. The sensors are intended for both upstream (pre-catalytic converter) and downstream (post-catalytic converter) positions and are sold as a set to simplify multi-sensor service.
