....They fit perfectly, they work perfectly, they tested them for us so I trust they are "the good ones", Suncoast is part of the Porsche world, so I like supporting them instead of some faceless eBay outlet, if they go bad, Suncoast is easy to deal with for returns, and they had a free shipping sale, so I didn't pay for shipping.
It's amazing to me that folks will spend the money to buy a Porsche, and then try to save five bucks on some widget.
Anyway, the Suncoast bulbs fit, work, and got here in two days.
