MZR-CD 2.2 Cleaning intake manifold and EGR system (Part 1)

Mazda 6 GH MZR 2.2 CD: How to clean the intake manifold and EGR system. This is part 1 where I show how to disassemble and clean. Sorry for the typos and misspellings.
My main goal was to evaluate how much dirt deposits are there and then clean the intake manifold and EGR stuff. I cleaned EGR 6 months before this job and decided to clean it again for the video sake and also to see how dirty it can get in 6 months.

Hello, what symptoms had this Mazda before cleanin intake mainfold?

Hi, there was no real issue. Before cleaning the intake manifold, I cleaned the EGR. It saved me 0.5-1L/100km fuel. I was surprised and decided to clean the intake manifold, too. It actually didn't affect fuel consumption. However, my boost pressure (calculated) increased up to 1.46 bar max (it was around 1.35 bar max before). I think either intake manifold gasket leaked or MAP sensor hose cleaning helped. So, I did it mostly for fun and possible profit. Usually, there are no significant issues if your intake manifold is not clean, just performance / efficiency hit.
