Intake manifold runners and plenum cleaning?

[Husam]

Hi everyone,

On a 2015 3.8 v6 Genesis, what is the most effective way to clean the intake manifold plenum and intake runners? Not the intake valves.

Is the manifold made of plastic, aluminum or steel?

Can we completely remove the intake manifold and manually clean it? Which cleaners to use? What is the cleaning process?


Thank you in advance,
Husam

I would not waste time cleaning the intake manifold, because carbon build-up seems to occur on the valve stems and inlet chambers surrounding the valves stems. However, you could probably spray some carbon cleaner like CRC in to the intake manifold runners with the intake manifold removed and let it drain out; which may clean out any carbon that may have formed inside the intake manifold.

The intake manifold is made of plastic, however our engines may also have a lower manifold as well that is metal.
