My plug of choice is the Motorcraft. It performs in the modular engine, and if you coat the shank in nickle antisieze, it will come out. None of mine broke without the antisieze. They last for 70,000 to 100,000.
If you just have to go one piece, it seems the best luck is had with Champion. There have been at least three guys on here that tried the E3 and had to take them out after 3000 miles or so.

What's the difference between Platinum and Double-Platinum? I've been given the SP-515's both times I've purchased them, but don't know the difference.
