Catalytic Converter

Catalytic Converter
This vehicle is equipped with a three-way
catalytic converter. The catalytic converter
contains precious metals that serve as catalysts in
high temperature chemical reactions that
convert hydrocarbons (HC), carbon monoxide
(CO), and oxides of nitrogen (NOx) in the
exhaust gasses into safe compounds.
A defective catalytic converter contributes to air
pollution and can impair your engine's
performance. A replacement unit must be an
original Honda part or equivalent.
