Whether you’re looking for a reduction catalyst or an oxidisation catalyst, you’re sure to find what you need in our range. Your engine uses catalysts in a number of ways. This includes helping to make sure the gases your car produces have as much oxygen in them as possible – your reduction catalyst is responsible for removing nitrogen atoms. Other functions of a catalyst in your car are to reduce the level of unburned hydrocarbons and carbon dioxide produced. This is the responsibility of the oxidisation catalyst. If you’re unsure about which type of performance catalyst you need, feel free to call our friendly team for advice. We also have over 200 branches nationwide, so you can always call in to speak to us in person. Alternatively, enter your car’s registration number on our site to find car parts for your vehicle.
