This Spacer is designed to space the oxygen sensor out of the hot exhaust gases just enough that it helps eliminate the check engine light (CEL) that is caused by a dying catalytic converters or catless exhausts. Some exhausts leave less room so a straight spacer may work better vs the 90-Degree depending on how tight the area is. Please confirm which style suits your needs before placing an order. This Spacer is made up of 304 high quality stainless steel. 

**Note: This Oxygen Sensor Boss is designed for off road/racing use and has not been approved by any international, federal or local governing agency for street use. Please research the emissions and legal requirements for your region.

Vehicle Fitment

  • All Vehicles with M18x1.5mm thread Oxygen Sensors

Be advised that these Oxygen Sensor Spacers may not fully remove the CEL on some of the new 2011+  Volvo vehicles. These newer vehicles are much more sensitive to O2 Sensor spacing.
