LONG extension cord for second O2 Sensor - for use ONLY when installing header into Miata already using ROADSTERSPORT or PPE MIDPIPE.

This is an option for aftermarket headers to allow relocation of your second factory O2 sensor to a position after the catalytic converter in a midpipe so that your installation is easy PLUG AND PLAY. Note that the plugs for each sensor are unique so that it is impossible to mix them.

NOTE: This is only plug and play for those with RoadsterSport midpipe or similar which provides a location in the midpipe after the converter for easy relocation of the secondary o2 sensor. If you have a factory midpipe, then you would have to get a bung welded in your midpipe for relocation of the o2 sensor.

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.

NOT CARB APPROVED, CANNOT SHIP TO RESIDENTS OF CALIFORNIA.

These wire extensions are made for us by a couple different suppliers, and visual appearance may vary depending on which supplier they come from. All versions perform the same, differences are cosmetic only.
