I went with Champion platinum plugs, which look exacly like the OEM AC plugs. So far, so good after 5,000 miles on them.
They cost $4 each.

The Beru's for the C5 have been available to the American retail consumer market for more than three years now. The Beru's are more known and common in the European exports market. Frankly, as an exotic alternative spark plug system, they are very costly (especially the specialty Beru spark plug wires for the Beru plugs).
Basically, you will see true performance gains only through real engine upgrades and mods such as cams, heads, intake, long tubes, etc. Spark plugs do not make a significant HP difference, if any, at all. As a suggestion, it is best to purchase the more accessible and reasonably priced popular spark plugs for the C5 by NGK, Bosch, etc. In fact, I have been installing the Platinum +4's on all my C4's and C5's since the Platinum version became available in the early ninety's. And, I have been happy with this spark plug product ever since. Good luck to you.
