The ITG induction kit for the Fiat 500 Abarth completely replaces the OEM intake system.  The ITG kit sources cool air from behind the scuttle panel, well away from any power robbing heat under the bonnet.
 
Testing has shown gains of 16hp over the standard induction system on a re-mapped car.
Aside from the increase in power, there are improvements' with throttle response and a pleasing, yet unobtrusive increase in intake noise.
