NEW 90° Pro O2 Sensor Spacer Mini Catalizador Mini Catalytic Converter to Fix CEL P0420 P0430

YEP! These work.

Installed these on my 260,000 mile GMC Sierra with a 6.0, constant engine light for catalyst efficiency low. Put these in on both rear O2 sensors and solved my issue. Better than a 1600 dollar replacement CAT on an old work truck! Thanks.

Worked exactly as advertised and cleared my error code for Nissan Xterra due to not having a Catalytic Converter.

Got 1 installed so far so good 👍
