Description
Bosch Super Plus spark plugs feature a heavy duty yttrium enhanced copper core center electrode for superior reliability and increased resistance to spark erosion. The tapered, v-profile nickel ground electrode provides improved starting in cold weather and increased fuel burn. The metal glass fused resistor allows for maximum interference suppression while the ribbed insulator design prevents misfires due to current leakage.
