They use a plug that's designed and manufactured to fit inside the
Mahle 'jet' pre-ignition chamber. There can't be a lot of call for
those as yet so it's understandable that they'd be quite expensive.
Seems they're made by NGK (you can read that if you scroll down a bit
on that previous link, past the Kubica report).
"Spark plugs on the Ferrari engines have been supplied by the NGK group,
whose parent company is based in Japan. On the current breed of hybrid power
units, each spark plug has its own coil and can produce up to 125 sparks per
second. The element is designed to withstand high stress, vibrations and
temperatures but it ended up costing Vettel crucial championship points."

little classification in the DSM*."
