Catch cans and connectors

No need for boiling water mate, just press the squishy bits of one end and unplug then rotate it to a comfortable position and press squishy bit of that and pull off.
If game enough, disconnect the intake from the main valve and give it a good clean.
If relatively new car as in there is less likely to be a lot of gunk build up and more game read up and see videos and if you think you want to use LiquiMoly intake cleaner.

Edit that kit looks very good but is the internal diameter also spiral or is that smooth??
