Pro-Sport O2 Sensor CEL Eliminator, mini-cat

Pro-Sport gauges and devices for accurate measurement.

Catalytic converter Check engine light, so called CEL.

This is something you might have got lighting up your dashboard, after installing high flow downpipe or a new catalytic converter from spare parts market.

Vehicles on-board diagnostic monitor the status of Catalytic converter in real time, and in case the flow or efficiency of this unit has changed – it will do as it’s programmed to do and inform the driver with catalytic converter check engine light.

Simple mechanical fix can be done with a Pro-Sport O2 spacer, that includes a miniature catalytic converter inside it. This is enough to correct the measurement enough to keep the systems happy.

• Standard M18x1.5 thread for common O2 sensors
• Available in direct and 90-degree angle
• Avoid check engine light from catalytic converter
• Choose type of the spacer depending on the clearance around your O2 sensor
• Remember that sensitivity of the system varies by car, 100% efficiency cannot be guaranteed.

Pro Sport gauges have been a staple in our customers shopping carts for many years.
