BMW Walnut Blasting

For those who have not heard of this process before, it may sound like an April Fools’ joke. However this is not only a very real, but extremely beneficial service you can and should, give your N54/N55 equipped BMW. Let’s take a closer look at what exactly is involved.


This is a picture taken from the intake ports of a motor with just under 100,000 kms on it. You can clearly see the deposits built up on the back of the valve. This can cause poor sealing, loss of compression, and in some cases even engine misfires.
In older generation cars the fuel injector was placed in the intake runner, before the valve. By injecting the fuel in this manner it doubled as a way to clean the back of the valves. With newer direct injection technology, the injector tip is now located inside of the cylinder, so this cleaning has to be taken care of in a different manner.

Here at Haute AG, this is the system that we use to restore engine performance. We have a pressure pot that is fed with regulated compressed air. We then have a mildly abrasive media of crushed walnuts.The walnut shells are specifically chosen to remove the deposits without causing any damage to the cylinder head or valves. lastly we use a a shop vac to remove the media as soon as it is expelled from the gun. The process takes a few hours to complete, and the intake manifold gaskets are replaced after the service.

Our clients have reported immediate engine response improvement, along with performance gains throughout the RPM range. So, if you are experiencing lackluster performance out of your twin turbo BMW, or have more than 55,000 kms, give us a call today and let us show you the difference our Walnut Blasting service can make!walnut_blasting
