Bosch's Platinum +4 premium spark plugs have a pure platinum center electrode and four nickel-ytrium ground electrodes," Bosch's Hallis explained, "and fire radially - rather than axially like conventional plugs - producing greater combustion efficiency.
The precious metals and the multiple ground electrodes resist the erosion of metal when the plug fires, preventing gradual weakening of the spark as in conventional plugs.
With the four ground electrode
design, the spark finds the most efficient path from the platinum center electrode, ensuring the least electrical resistance.

2 /PRNewswire/ -- The editors of Popular Mechanics have chosen Bosch's Platinum+4 four ground electrode
spark plug as a winner of its 2000 Design & Engineering Awards.
Furthermore, the sound could be altered by turning the oven on and off despite the ground electrodes
being more than ten meters away.
A competitive product consisting of ground electrodes
produced an irregular aggregate with an extreme surface area, which required excessive amounts of binder to coat and bond.
The headset's reference and ground electrodes
are on the ear clip and the EEG electrode is on the sensor arm, resting on the forehead above the eye.
Champion premium plugs for automotive applications include Champion Iridium, bringing maximum performance and exceptional durability to any engine model; Champion Double Platinum Power(TM), featuring platinum on both the center and ground electrodes
for longer lifer and minimal wear; Champion Platinum Power(TM), an ideal upgrade for engines equipped with standard nickel/copper plugs; and Champion Truck Plug(TM), ideally suited to the severe demands of today's pickups and sport utility vehicles.
The ideal choice for hundreds of popular vehicle makes and models, Champion Double Platinum(TM) spark plugs feature platinum center and ground electrodes
matching the specifications of the world's leading vehicle manufacturers.
For example, PowerSport plugs have a "power boost firing end" with center and ground electrodes
positioned deeper in the combustion chamber than typical plugs.
