Has anyone used CRC Intake Valve Cleaner?

I've been looking into ways to maintain my GDI engine and doing a cleaner like this seemed like Iíd be a good option. Iím at 24,000 miles on the 2018 1.6 Turbo DCT.

Problem is that youíre supposed to spray it in past the mass airflow sensor, but I canít find the dang thing. Have any of you used this CRC cleaner and where did you spray it in on?

Or, if you know where the MAF is supposed to be that would help.

Thanks in advance.

Theres no mass air flow on these. Theres 2 MAP sensors. One on the intake manifold and on the cold side turbo piping near the blow off valve. Take off the breather hose at the back side intake hose that goes to the valve cover and spray in there. Do not let the straw get sucked into the intake hose that would make for a bad day.
