Unique four ground electrode design. 75% more pure platinum vs.Bosch Platinum. Gap is pre-set at the factory. Four ground electrodes provide optimal access to the air/fuel mixture for the most efficient combustion and longer life. Pure platinum technology. Only Bosch uses a pure platinum center electrode that's heat fused, to reach its self-cleaning temperature faster for smoother acceleration, improved fuel efficiency and optimal engine performance. Platinum + 4 adds 75% more pure platinum to its center electrode than Bosch Platinum. Only Bosch adds an Yttrium alloy to its four ground electrodes, providing up to double the wear resistance of a standard plug ground electrode. The gap remains unchanged, providing a longer performance life.
