The intercooler spray on my 4 hardly ever gets used, switch in a silly place really. Anyway, browsing through the Demon tweeks catalouge I noticed an electronic fan control unit ( top of page 205 ) that is fully adjustable, and looks easy to fit. Now this unit is to be plumbed into the cooling system and switches you electric fan on. Could this be modified ( bodged ) to fit into the intercooler pipe work somewhere and fire of the cooling spray in short bursts when it senses it needs it ? I know other people sell the correct bits to achieve this but they seem a bit on the dear side, this one only costs £ 35 |PLS| the vat. What do we think ?
