O2 Sensor

[GeminiMike]

I heard via via someone said something about a replacement O2 sensor for the E46 that is kind of like a dud sensor that's tricks the motor into thinking its still there however this sensor is much better than the original giving better fuel consumption and engine power.

Has anyone hared of this before and if so where can I get one?

I think you are talking about a Mini CAT/CAT fooler. You put this on after doing a decat (Your Post CAT O2 sensor is plugged into this CAT fooler) so the engine light doesn't trigger and the ecu is fooled in thinking the CAT is still there and a result is slightly less consumption after Decat.

So Yulesen, where can I get one?

Most exhaust shops have it. Have you done a decat? I got mine at Powerflow
