My thinking was that if you heat up the intake slightly, the net gain would increase slightly - let me explain. I have no idea of how much temperature gain/loss happens when the air is compressed and cooled, so I'm making wild guesses - purely for example purposes. Let's say the air going in is 20 degrees C, gets heated up by the turbo by 50 degrees to 70 degrees C, then cooled by the intercooler by 30 degrees C, and the net result is 40 degrees C going in the engine. So, if I re-route air intake and achieve a 5 degree C increase in the intake, so 25 + 50 - 30 = 45 degrees C. I don't have a degree in thermodynamics, so I could be completely wrong.
However, this line of thinking is moot, as quite a few people have pointed out that a turbodiesel would benefit more from a cooler intake, rather than a warmer intake anyway, so I'm dropping the idea.
But, I will accept that tasty beverage from you

OK will do that. What sort of material is good to use to extend the intake pipe - I'm a little worried about trying to attach the hose over the flared end. Should I shape the start of the tube as a small funnel to "collect" as much air as possible, or should the start just be straight? Sorry for not being very clear!
Thanks to everyone else for your advice, much appreciated!
