Anone know of any that do, and if so, do they?

I have owned an 85 VW golf, a chevette, and 2 geo storms. I tried Bosch platinums in every one of them, and they all failed after 100 miles -- misfiring, bizarre idiling, etc. . . .I always then replaced them with the cheapest AC delcos or NGKs I could find -- being all ticked off at blowing all that money on the Bosch platinums, and I never had a problem. I ain't a big fan of Bosch, but NGK and AC delcos are good plugs IMHO.

When you say "failed", do you mean fouled or what? Ive used Bosch Platinums in many of my cars and they always made them run great. Smooth and sure firing. You were putting them in pretty old cars and I wonder if the problem wasn't the plug, but the engine. Were they gapped correctly?

That's the biggest thing: you have to be very particular in your gapping. The only plugs I've seen that are truly "pre-gapped" are the Bosch +4's and +2's. They don't have any adjustment. I used Bosch in my 88 S10, and to this day they run perfectly. All in the details, IMO...
