A set of four 4-wire oxygen sensors with factory-style wiring, harnesses and connectors, so they plug into the original loom and thread into the existing bungs. Each sensor uses a zirconia element for a fast response to air-fuel changes, and the outer shell is built to resist silica and other contaminants. The set suits a V6 or V8 owner replacing all sensors at once, which is the usual recommendation when one fails on an older engine. Against single-sensor buys it saves repeat labor and keeps the bank matched, but it is a general-purpose fitment, so confirm the connector and thread match your engine before ordering.
