Keep your vehicle running at its best with Holts EGR & Carb Cleaner – this 500ml spray ensures a thorough cleaning of your car’s EGR system, increasing energy efficiency and throttle response.
Engines with Exhaust Gas Recirculation (EGR) systems can suffer from the build-up of harmful deposits over time, and that’s why it’s so important to use an EGR cleaner – the powerful formula prevents soot from building up in the system.
This aerosol works upside down and offers 360° spray to make sure you reach those hard-to-access areas. It removes build-ups caused by petrol in carburettors, and carbon from recirculated exhaust gases in diesel engines.

• Suitable for petrol and diesel engines
• 360° spray to access hard-to-reach areas
• Removes build-ups and carbon deposits
• Increases efficiency and throttle response
• Thoroughly cleans your car’s EGR system
