Walnut Blasting

Walnut Shell Blasting – For BMW & MINI

The Benefits

Modern engines utilize direct injection, this allows for better performance and fuel consumption. The disadvantage of Direct Injection is that the regular fuel bathing and cleaning of the intake valves does not happen anymore. Over time this leads to carbon build up inside the intake tract and on the valves themselves. This does not cause any immediate risk to the engine, however over time as the carbon builds up it can affect the efficiency of the engine, causing performance issues and increased fuel economy and oil consumption.

The engine inlet chamber and inlet valves are cleaned of carbon build up that is a common problem on modern direct injection engines. The De-Coke procedure is carried out via walnut shells being blasted into the chamber.


We use the same Walnut Shell Blasting kit as BMW/MINI main dealers

Walnut Blasting cleans the intake tract and valves without the need to remove and strip the complete cylinder head to allow the valves to soak in a cleaning solution and manually clean them. An expensive job that would have taken up to 24hrs.

The blasting tool works using pressurized air to inject fine walnut shells into the intake tract, the walnut shells attack the carbon at high speed removing it completely without causing any damage or negative effects to the engine, walnut shells do not cause any damage whatsoever to the intake tract and valves or your engine.
