User/Installation Manual
Product Description / Features
The ?Intercooler Spray Controller is a ’smart logic’ controller which
adaptively monitors how hard the car is being driven to determine when the water spray
directed at the intercooler should be activated. It can be used on any turbocharged or
supercharged cars fitted with an intercooler and air flow meter (AFM or MAF), regardless of
fuel delivery system.

By measuring the temperature of the intercooler core or intake air temperature relative to
ambient temperature as well as the volume of air used by the engine, the controller
determines when to switch on the water pump. The pump is only activated when it is really
needed and water consumption can be drastically reduced, with no reduction in cooling
performance.
If the turbocharger or supercharger is producing boost…
