I just watched a review for a 2024 M4 where the guy was running catless downpipes and using some mini "CATTED" O2 bungs. He claims to have driven a couple of thousand miles with zero CELs. These are the items in question

Has anyone here used these and had any experience with them?

I believe this topic was very briefly touched on before but didn't really go anywhere.

Thanks.

I have used something like this on a Honda and no cel. It is basically a spark plug fouler you screw into the post o2 sensor port and screw in the o2 sensor into the fouler
It tricks the o2 sensor.
