Why Does a Catalytic Converter Cost So Much?

Catalytic converters are expensive because of the precious metals used to make the part.

The part uses precious metals like platinum, or platinum-like materials such as palladium and rhodium, as a catalyst.

These metals are hard to find and can cost between £30 and £600 per gram.

As these prices continually fluctuate, it can be difficult to predict how much a catalytic converter will cost.

Your car needs to be lifted off the floor – something a mechanic may require specialist tools to do.

This means you may end up paying higher labour costs as this is a major job.
