The Vibrant Performance VIB11620 oxygen sensor extension features a J-bend design to move the O2 sensor out of direct exhaust flow, helping to prevent fouling and extend sensor life. Manufactured from high-quality T304 stainless steel with a natural finish, it offers superior corrosion resistance and durability. Designed with a male 18mm x 1.50 thread, it is compatible with standard oxygen sensors and ideal for performance or custom exhaust applications requiring repositioning of the sensor. Sold individually, it is discontinued, therefore once our stock sells out we will not be restocking it.
