Doing an aftermarket downpipe install?

Aftermarket downpipes often relocate the rear oxygen sensor farther away, leading to stress on both the harness and sensor that can result in failure. iWire's rear oxygen sensor extension lengthens the connection by 7 inches, adding the necessary length to allow any downpipe sensor connection to reach with ease.

Built with military grade materials to withstand the harsh environment underneath the car that includes heat, vibration, and debris. Standard length is 7 inches.
