I have heard a lot about `Sea Foam` and would like to try out in my `mazda 3 2010`. I am planning to put a can in the `Gas Tank`, half a can in the `Crank Case` and remaining half into the intake through `vacuum line`.
Unfortunately I am not very sure about the vacuum line, please help me if the following is the Vacuum line which can be used for the same. My earlier plan was to use the `Sea Foam spray` through `throttle` but unfortunately `spray` is not available in the Philippines (only motor treatment is available)

PS: Most of the videos or online instruction for Mazda is for 2.0L or 2.3L engines, I would like to confirm the same for 1.6L engine
