As far as I know, this is required for the 02 Sensor to reach on the passenger side.Those with an 18 and headers. What you you guys doing for the o2 sensors since they are different?
Supposely ARH have a extension part SH311. Nobody carry it that I know. Cjpp can`t help either I think they prefer to sell the 115$ new sensor when all we need is a extension.As far as I know, this is required for the 02 Sensor to reach on the passenger side.
