i don't think the n52s need it done just because the fuel supply is different fuel supply, i think the fuel would clean your intake valves. but for us our turbos shit oil and no fuel passes over intake valves because the direct injection, therefore the build up occers. you could probably use octane booster or techron to clean yours up
