Intercooler success.. Almost .. Need some diameters

Hi all

Recent had fitted a universal intercooler kit and had a lot of success with two minor hiccups...

The straight plastic hose that runs alongside the block from top (of the engine bay, if looking in) to the L shaped hose that fits the standard intercooler. This pipe is narrower than the hose kit I have fitted for the Fmic. So wanted to grab a forge diameter converter hose... But I don't know the diameter of this hose.

Any ideas?

Secondly I am in need of a place to put the map/thrust sensor... At the mo it's bogged into an Ali pipe and leaking boost (whistling). So wanted to know if the forge one is worth it
