hmm, i'm very interested....
My cooler (GReddy type M) is really efficient. Qualify: the inlet side of the cooler is damn hot, can't hold hand on it for long after spirited driving, and the outlet side is quite cool, just like metal thats been out of the sun...
On the other hand, the pipework that runs behind the radiator is damn hot... I would be very interested in something that reduced the pipe's heat and also made it look less aftermarket when the coppers open the lid....
(I believe they wont be able to see the fridge door cooler at the front, they'll look straight past it)
