Walnut Blasting

[trabuccomlfrd]

Has any one had any experience with walnut blasting of the valves on their ecoboost?? My second vehicle which is a Mini Cooper John Cooper Works edition just had it done and it made a night and day difference. Is this an acceptable cleaning method for an ecoboost engine?

A best way by which one can remove and clean carbon which is deposited in the internal port of the vehicle.
Well, just for the curiosity are you looking to purchase it?
