A induction cleaning is a professional 3 part fuel injection cleaning system.The 1st step is a highly concentrated injector cleaner that is poured into the gas tank,more powerful then any store bought stuff,including SeaFoam.The 2nd part is the intake/valve cleaning which uses another highly concentrated cleaner that is sucked in through a vacuum line while the engine is running.A special bottle is used so you do not hydrolock the engine.The 3rd step is a throttle body cleaner,also used as the engine is running.
It's a very effective cleaning system,just alot better and more potent then SeaFoam.
The service that Precision lists on their site does not say anything about the fuel system, just the air intake system.

We introduce a special cleaning agent into the intake manifold with the engine running. This agent dissolves the carbon deposits, which are then emitted out of the tail pipe.
