I just installed my 3 bar today and I decided to take the intake tube off and have a look. My car is at 19k miles and it looks spotless inside. My intake tube is dry to the touch and as far as I can see the intake manifold is like new. I ordered a snake cam and I'll post pics next week.
I think the carbon build up is hit and miss.
