**helps to get rid of checking engine lights.**

Oxygen O2 Sensor Adapter CEL Eliminator With Catalytic Converter:

Features:

• Built-in M18X1.5 catalytic converter, helps to get rid of checking engine lights           

• General model is suitable for most automobiles            

• Built-in micro catalytic converter, avoid checking engine lights after modifying exhauster or removing catalytic converter      (This item can't completely replace the catalytic converter, you still need a catalytic converter)        

• This O2 cel fix with a miniature cat will trick your ECU into thinking the stock catalytic converter is still installed. When you remove your catalytic converter, your post O2 sensor will see higher temperatures and greater flow of unburnt fuel. As a result, this will throw check engine lights (Cel, SES, DTC) typically the error codes will be P0420 (Catalyst System Efficiency Below Threshold Bank 1) and/or P0430 P0420 - Catalyst System Efficiency Below Threshold Bank 2). But for OFF ROAD use only!!!

• DESIGN TO FIT MOST VEHICLES WITH THE M18X1.5 O2 SENSOR HOLE.
