AEM Electronics Infinity O2 Sensor Extension Harness - Universal

AEM Infinity O2 Sensor Extension Harness Universal The AEM Infinity O2 Sensor Extension Harness is available for those of you who might have your wideband O2 sensor welded in a location that is far out of reach in some instances, and you need more harness to make the connection. In some aftermarket exhaust systems, some O2 bungs are welded close to the mouth of the downpipe, while others are welded further down the pipe. Whatever the case may be, this extension is approximately 72" long, which provides the user with plenty of room when custom installing a gauge.
