If you get the car from the factory with X51, the PSE comes with it. If one buys the kit from the dealer, then there is a choice to buy it for those who do not have PSE already, or not to buy it if you already have PSE on the car. The third radiator is part of the kit either when installed at the factory or if purchased from the dealer. Apart from all the hardware, there is also a software update as well as getting an "S" stamped on your engine serial number at its end.

 

Either way it looks good and sounds just as good im sure at higher rpms. Congrats on ur new arrival and bringing it home like a boss!

 

Sweet pickup. Enjoy the new Porsche feeling!
