I actually pulled the vacuum hose off of the brake booster and sprayed it through there. Just be careful if you go that route as it’s a more direct shot into the intake manifold. Not that you would necessarily risk hydrolocking the engine, but why take he chance? Two to three second bursts. Next time I will shoot some through the intake as well to get any potential blow-by oil from the PCV system off of the turbo compressor/impeller blades.

You could remove the the air box, stick the straw/tube from the GDI cleaner in past the MAF, and you’ll be fine.
