anyone still using silver spark plugs?

[scott thomas]

I remember my first 5kt had them and I did like them, but didn't use
them long enough to know about their life. A few sites do still list
the w7ds's, while Beru Silverstones are being marketed by
the "performance" dealers.

Just wanted to know if they last long or not at a savings over the
w7dpo. My dtc's don't last so long because of how many miles I drive
in a short time.
