Description:The micro-catalytic converter integrated into the O2 cel fixture helps to eliminate this annoying problem by performing a light check on the engine after replacing the exhaust pipe or removing the catalytic converter, sometimes even when installing a high flux catalytic converter.The opportunity should not be taken simply because the length does not usually work. This is effectively an integrated micro-catalytic converter.The cel curing will make your ECU think that the catalytic converter is still installed. When the catalytic converter is removed, the oxygen sensor will see an increase in temperature and an increase in the flow of unburned fuel.
