Triple electrode spark plugs

[Philippe-J.]

I red in the Gazoline french magazine a short letter by one of their readers, praising the triple electrode spark plugs. The E Type was one of the examples of successful application, but no detail was given about which model and where to purchase them.
Has anyone here tried those? What identification number? Where to buy them?
Thank you in advance for your comments.

For many years I use the Bosch WR78 Super 4 spark plugs in my E-Type S2 and my Healey 3000.
Both engines are mildly tuned and run just fine with the 4 electrode Bosch.

Kind regards
Frank
