90° M18 X 1,5 vinklet O2 Sensor Extender Spacer Oksygen Bung Extension

works as described. im running a catless header and it definalty tells the ecu rhat the down stream is reading a different fuel mixture and the p0420 code is no longer command on, got like 800 miles on it

The previous owner deleted the catalytic converters on my 2003 Toyota Tundra so the Check Engine Light (CEL) was always on. Since I have no catalytic converters, I know that code will still be there. Adding these O2 spacers allows me to still see when the truck's computer detects other issues.

I am very happy that this product worked on my 2016 Ford Explorer Limited. It was a bit difficult getting the O2 Sensors loose from the Catalytic Converter, but once I got them off these adapter went on very smoothly. Don't forget to apply the copper goop (purchased separately) so that they can come off easier in the future if necessary. I drove the car for about 50-miles afterwards and the P0420 & P0430 permanent error codes went away. I should also mention that I also first used a bottle of Cataclean in the Gas tank first to get rid of the error codes, but it did not alone resolve my issues. I am so happy now I have no engine light or error codes and I can now pass Smog inspection.

Well the part look so good! I didn’t have time to install because just arrive this weekend and for the next weekend I’ll be installing! And hopefully will fix the issue P0420

It works like a charm. Check engine light went out in a day!
