Every walnut blasting service is priced dependent on the labour required to remove the intake itself, the units of compound used for the service and the replacement new gaskets to complete the service.

The average cost of a walnut blasting service ranges from $600 to $1300, with the final price varying dependent on vehicle specifics.

A walnut blasting service length of time is subject to each vehicles make, model, presence of modifications, and extent of carbon buildup.

To perform a walnut service all components are required to be disconnected from your inlet manifold so that it can be removed and your inlet ports accessed. The length of this process is dependent on the make and model of your vehicle.

The inlet ports, walls, valves and stems are walnut shell blasted, cleared and restored. The inlet manifold is also cleaned if required. The length of this process is dependent on the extent of the carbon buildup.

Before reassembly, the old manifold gasket is replaced with a new manifold gasket. Once assembled, a diagnostic scan is performed reset and clear any error codes on the vehicle.

As a result of environmental regulations and operational requirements the induction system of modern engines are responsible for the processing of unsafe crankcase and exhaust gases.

A consequence of this is seen as a buildup of heavy carbon deposits which block and choke induction ports and valves. With this buildup increasing substantially if non-premium fuel is being run through the vehicle.

In a direct Injection system your fuel is 'directly injected' into the cylinder combustion chamber. With this, even if using a premium fuel with additives, your valves and inlet ports are not able to be cleaned and carbon buildup forms.
