Intake Cleaning on Q45

[firstq]

Guys - what is the recommended process for performing intake cleaning?

I have the injectors and fuel rail all clean during the plenum job - would like to clean up the intake.

What chemical and what vacuum line to use? Does the brake vacuum line port into the plenum usable for injecting the intake cleaner chemical in?

The booster connection does not flow into the intake properly for cleaning. Use the connection at the charcoal canister with vacuum while the engine is running. After cleaning leave the hose open to pull the rest of the fluid out of the hose. The BG cleaner seems to be the most popular on the site, there are some other posts that reference where to get cleaner and I'm sure someone will add where they get cleaner.
