1996-2001 Acura Integra GS, LS, 1.8L 4-Cylinder Catalytic Converter

Inside a catalytic converter, there is typically a piece of ceramic coated with various precious metals, including palladium, rhodium, and platinum. These are the “catalysts” that create a chemical reaction to convert harmful gases into safer substances.

The piece of ceramic in a catalytic converter usually looks like a honeycomb. It is shaped that way so the gases can more easily flow through.
