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% vs. original Bosch Platinum, reducing electrode temperature, and improving access to air/fuel mixture; Nickel-plated rolled threads is used for complete anti-seize and corrosion protection; Lower ignition voltage requirements vs. other plug designs for reliable cold weather starts and superior operation under all driving conditions
