HEADER INSTALLATION LONG extension cord for second O2 Sensor....for use ONLY when installing header into Miata already using ROADSTERSPORT MIDPIPE.

This is an option for the RoadsterSport header and Racing Beat Header to allow relocation of your second factory O2 sensor to a position after the converter in a RoadsterSport midpipe that so your installation is easy PLUG AND PLAY. Note that the plugs for each sensor are unique so that it is impossible to mix them. Extension cord uses thermal insulated wire and factory connectors and care should be take to make sure the connectors do not contact the hot header because while the wires are thermally protected the connectors can melt if left in contact with the header.
