Product Description

304 Stainless Steel Check Engine Light Adapter

𳦾ھپDzԲ： Name: CEL Eliminator M18 X 1.5 Oxygen Sensor Adapter with Mini Catalytic Converter Fit for: Most modern vehicles equipped with M18 X 1.5mm threaded oxygen sensor Thread: M18 X 1.5 Materials: 304 Stainless Steel Color: Silver

Package Included: 2pcs x CEL Eliminator with Mini Catalytic Converter

304 Stainless Steel Check Engine Light Adapter

304 Stainless Steel Check Engine Light Adapter
M18*1.5 O2 Oxygen Sensor Extender Spacer

A built-in micro catalytic converter can eliminate the CEL that is less efficient than the catalyst, helping to get rid of the annoying situation of checking engine lights after refitting, installing or removing the catalytic converter.

304 Stainless Steel Check Engine Light Adapter

HOW IT WORKS?

When a high-flow catalytic converter is installed in your car, your engine inspection light (CEL) may illuminate due to increased airflow. The oxygen sensor gasket separates the rear oxygen sensor from the exhaust gas path, making the vehicle's ECU think that the original catalytic converter is still in place.

  • The compact design and modular accessories allow it to be installed in areas with limited space, which enables efficient use of space and avoids damage to the oxygen sensor
  • Made of high-quality 304 stainless steel, it can greatly avoid cracking and excessive thermal expansion, and can be used for a long time.

    Been one month no CEL, all city driving so can't speak on highway. But def works and good quality product overall.

    Update : after 1.5 years of driving, the mini cat inside the fowler started dancing around making a pinging tin can noise and I had to remove one but the other one was fine, unfortunately check engine light came on after removing the mini cat, not a bad product though

    I was actually surprised. I have a 2005 nissan pathfinder. I have the front cats gutted and recently added these to my 02 sensors.... these cleared one of my 2 check engine light codes. I installed bank1 (passenger side) and bank2 (driver side) and bank1 inefficient cat code cleared ... bank2 p0430 stayed on still.. so it helped a bit. I may try and reinstall the drivers side one again see if it clears it up. But still, it helped my 02 sensors not cause my truck to run so rich.

    5.0 out of 5 stars Finally got rid of my CEL
    Reviewed in Canada on September 5, 2023
    Verified Purchase
    2001 Jimmy with 4.3 motor. Catalytic converter was plugged up and had shop install cat delete pipe. I didn't want to spend 800.00 for a new cat for a 23 year old vehicle. I have tried 2 other types of O2 sensor extenders similar to these, but with out mini cats and they didn't work and thought that I would have to live with the CEL on forever. But it was driving me nuts, so I thought I should try 1 last time. First installed 1 mini cat and light came back on, within 20 minutes of driving and thought this is a lost cause, so I used 2 and It's been a week and no more CEL and I'm happy as a pig in mud...lol!
    Update: Jan 10/24
    Working great! still no O2 sensor codes have come back since installing and 3700 kms. Before I installed these, my CEL came on 20 minutes or less after erasing error code.
