• CORRECTLY DIMENSIONED -thick enough so it won't warp when welding, CORRECT LENGTH so that the sensor is in the exhaust stream but not too far, so it does not obstruct flow, this is important as most of our customers are tuners and want max performance. Beware some other bung adaptor or nuts are to thin, they will warp and leak or ruin the threads and they are a big pain to seal and have the correct O2 reading to the ECU
