Exhaust sensor spacer or catalytic converter sensor spacer. Price per piece is 80 (only). Limited quantity. If the catalytic converter is emptied of its catalyst material, the computer scan will show codes P0420 and P0430. The following problems may appear: 🚨 4 cylinder (small cars) 80 SAR 6 and 8 cylinder 100 SAR (the piece is larger and withstands high temperatures) Check engine light illuminates on the dashboard Noticeable increase in fuel consumption Strong carbon smell from the exhaust The spacer does not perform the function of the sensor. This means the sensor must be in good condition.. The spacer works when the catalytic converter is emptied; it acts as the catalytic converter. So, if your car has codes P0420 and P0430, the spacer will hopefully work for you. Benefit of the spacer - : Turns off the check engine light by providing a correct reading to the car's computer Reduces fuel consumption correctly Eliminates strong carbon or gasoline smell - Stabilizes the pressure gauge. Note: Fits all cars))) 🚗🚗For 4-cylinder cars, only one spacer is needed. For 6-cylinder cars 🚙🚐two spacers are needed. For 8-cylinder cars, two spacers are needed🚐🚙
