Never heard of a Porsche X50? Most people haven’t. But don’t be confused; it’s a factory option package, not a stand-alone Porsche model.

Here’s what Motortrend wrote about the X50 Power Kit in 2003:

“The X50 package must be specified at build time and cannot be retrofitted. The substance of it resides beneath the [911] Turbo's rear wing in the form of modified turbochargers (more boost), larger intercoolers, and more aggressive engine-control programming. It takes the standard Turbo's 420-horse rating up to 450 and creates a choice in between the Turbo (base MSRP of $116,200) and the 462-horsepower, rear-drive-only GT2 ($181,700). The upgrade costs an additional $17,880.”

The 2019 Porsche 911 Targa 4S above, available for sale at Isringhausen Porsche, is equipped with an X50 Power Kit. It offers superior performance with a retractable Targa top, plus the peace of mind of a certified pre-owned warranty.

Test drive it today at Isringhausen.
