Mini Catalizador O2 Sensor Spacer CEL FIX P0420/P0042/P0430 Code Universal (90 Degree)

The darn thing works!

My downstream O2 sensor kept throwing a code after about 60 miles of driving. I’d heard about these before and decided to give one a try. After two tanks of gas, still no check engine light. Installation only took about 10 minutes, and everything’s been running great since. Definitely happy with it.

2020 Hyundai Tuscon. I live in New York had a P0420 code I used the 45 degree spacer and code went away. I ran it threw the drive cycle 2 days, there went and got Inspection and passed. Would highly recommend.

I haven't had a check engine light for the last 200 miles since putting this on my chevy cruze and my gas mileage has increased a few mpg. Before with a regular spacer, my cel would come on about every 20-50 miles.
