<b>Product Description</b><br> When installing a high flow catalytic converter on your car or truck your check engine light (CEL) may illuminate due to an increase in airflow. An oxygen sensor spacer spaces out the rear oxygen sensor from the path of exhaust gases. This tricks the vehicle's ECU into thinking that factory catalytic converter is still in place. There is NO GUARANTEE this will prevent a CEL on your vehicle because modern ECUs are very complex and rely on a variety of factors to determine if the catalytic converter is working properly. <br> <br> <b>Specifications:</b><br> 100% Brand New, Never Been Tried or Installed<br> Thread: M18 X 1.5mm<br> Materials: Stainless Steel <br> Size: 32mm/1-1/4inch <br> <br> <b>Package including: </b><br> 1Set x Oxygen Sensor Spacer (2Pcs) <br> <br>
