it did the job
Car passed smog no more check engine light definitely worth the money
Check engine light went out at startup very pleased
Fit and worked perfectly to clear p420 code
So far after 300 miles the check engine light has not came back on. Hopefully it stays that way. Much cheaper option than a new catalytic converter.
good quality really good price excellent seller really good communication delivered really fast really recommend
Works like a champ
Excellent fit so far so good car working great.
This part is exactly what I needed. It also arrived to me quite quickly. Great service.
Simple install for anyone who can turn a wrench. Used red lock tight for the screen cap. Well over 200mls and no engine light so far while running my tuner and fuel economy went back up as well. Noticeable difference in idle and exhaust in higher rpms
This worked great on a 2009 Chevy Cobalt 2.2L with CA emissions but is in another state.
So far so good thanks guys!
Angled O2 bung extension works perfectly, and check light went away. Highly recommended.
Good product, fast delivery, great service
With the poor quality these days of aftermarket cat converters, these are the only way to keep the engine light out. Factory cats are to expensive.
Fit well.. worked as advertised.
Easy to install and effective
Works like a champ!
It's great no oxygen sensor code anymore. Shipping was very fast. I'm satisfied and I recommend to everyone.
Did nothing, made car run bad, definitely not for every car
Hi,
We’re sorry to hear that. Let’s go step by step and keep it simple.
Please check the following:
Installation Position
Make sure the mini catalytic converter is installed on the downstream O2 sensor (after the main catalytic converter), not the upstream sensor.
No Exhaust Leaks
Confirm there are no exhaust leaks near the sensor location.
Clear the Code & Drive Cycle
Clear the code after installation and drive the vehicle through a full drive cycle (about 50–100 miles mixed driving) to allow the ECU to relearn.
Sensor Condition
Make sure the O2 sensor itself is not faulty or heavily contaminated.
If possible, please take a short simple video showing:
Where the product is installed
The dashboard showing the code
How the car is running
This will help us quickly identify the issue.
If after completing these checks the problem still cannot be resolved, we can provide a full refund. We’re here to help and will make it right.
Got 315,000 miles,I'm sure the the cats are pretty nasty..
Got the P0420 code...installed the Sensor 02 spacer last week..I drive the vehicle about 200 miles a week, No codes so far...
Great
Worked awesome! I installed it and did not erase the PO420 code. I waited for it to go off on its own and it did! Took all day for the car to reset but that's ok, I had a trip to make anyway. THANK YOU!
great quality, easy to install. working as expected.
