Catalytic Converters

Understanding Catalytic Converters: Have you ever wondered what the small and shiny box-like component beneath your car withstands the heat and noise of the engine? That’s the catalytic converter responsible for cleaning the toxic gases produced by the car’s internal combustion engine.

Without it, our cars would emit harmful pollutants into the atmosphere that could cause respiratory and environmental damage.

In this blog post, we will take an in-depth look at catalytic converters, what they do, their importance in vehicles, and how much it cost to repair or replace one in Ireland.

What is a Catalytic Converter?

The catalytic converter is a device that converts harmful pollutants such as nitrogen oxides (NOx), carbon monoxide (CO), and unburnt hydrocarbons from your car’s exhaust system into less harmful substances like carbon dioxide (CO2), nitrogen (N2), and water (H2O).

What is a Catalytic Converter

The converter consists of a ceramic honeycomb loaded with precious metals like platinum, rhodium, and palladium that act as catalysts to react with the exhaust gases.

Why is a catalytic converter important?

Catalytic converters play a crucial role in reducing the amount of harmful pollutants released into the atmosphere.

Without them, cars would emit various substances that are harmful to human health and the environment.

These pollutants not only cause smog, but they can cause respiratory problems, heart diseases, and even cancer.

That’s why the European Union (EU), and other regulatory bodies worldwide, have imposed strict regulations to ensure vehicles reduce their emissions.

How much does it cost to repair or replace a catalytic converter in Ireland?

The cost of repairing a catalytic converter in Ireland can vary depending on the make and model of your car and the extent of damage.

A damaged converter will reduce your vehicle’s fuel economy and performance and will produce incorrect readings on your car’s OBD (On-Board Diagnostics) scanner.

The cost of repairing or replacing your catalytic converter for a standard family car can range from €500 to €1500.

However, the final price can be much higher. If you have a high-end car, the cost can be anywhere between €2000 to €5000.

Can you replace a catalytic converter yourself?

Replacing a catalytic converter is not a DIY job. The converter is a crucial component that is integrated into your car’s complex exhaust system, and its replacement requires specialised tools and expertise.

You will need to consult a qualified and certified mechanic who can replace your damaged converter.


Catalytic converters are essential components in reducing vehicle emissions that are dangerous to health and the environment.

They play a crucial role in minimising air pollution and reducing the risk of respiratory problems, heart diseases, cancer, and other health problems.

Therefore, it is essential to maintain and replace them as necessary.

If you suspect that your car’s catalytic converter is faulty, you should take it to a professional mechanic to assess and repair the damage.

Get the repair done sooner rather than later to avoid even more significant expenses in the future.
