Anyone ever see a sparkplug like this?

This is an AC Delco VF438LS. A buddy bought some off ebay and they look pretty interesting...

No, what are they for. No Gaping?

yeah, i havent used one but they have different gaps (because they cant be set) and are basically a better designed bosch +4. they are supposed to work well since its an open faced spark.
