This is a fail proof, plug & play kit for the X3's that give YOU full control of your Intercooler fan. The factory fan for the 120hp models will not turn on at all, the 154+hp models ONLY turn on under 80% load. This kit allows the IAT's to be lowered by maintaining cool air passing the through the intercooler even at cruising speeds. Cooler IAT's = MORE POWER! 

*Required component for 120HP X3's doing a intercooler upgrade.  The factory ECU will not turn on the fan!

*For already intercooled models this is an over ride that allows you to run your intercooler any time at the flip of a switch. Your factory intercooler settings will still activate the fan, however this allows you to turn it on even sooner!
