The air pump is the most important asset towards reducing CO in a
catalyst-fitted auto. In order to turn the CO into CO2, the catalyst
requires a source of oxygen. The air pump adds air (and therefore oxygen)
to the exhaust between the manifold and the catalyst so that the converter
can do its job.
