Only Bosch uses a platinum center electrode, heat-fused into an extended insulator that reaches self-cleaning temperature only seconds after starting. Tapered, yttrium-enhanced v-profile ground electrode extends service life by 25% versus original Bosch Platinum, reducing electrode temperature, and improving access to air/fuel mixture. Lower ignition voltage requirements versus other plug designs for reliable cold weather starts and superior operation under all driving conditions. Center Electrode Core Material: Platinum - Center Electrode Tip Material: Platinum - Ground Electrode Tip Material: Nickel-Yttrium
