Supercharging that gains 60 HP for $5000 for the X3? Please back up this opinion with facts. Looks like it is erroneous for availability(no one makes it for X3) and price (BMW superchargers for other models begin at $8k+ without installation). Where can this fantasy product be purchased? Be specific. Provide website info.
2008 BMW X3
2006 Porsche 997 2S Cabrio
