Spark Plug, 14mm Dia, 12.7mm Reach, Platinum (Replaced with W8AP+)

Bosch uses a platinum center electrode that's heat fused into the extended ceramic insulator.  Bosch platinumseries spark plugs reach self cleaning temperature faster for quicker starts, smoother acceleration and increased fuel efficiency.  The tapered, v-profile nickel ground electrode provides improved starting in cold weather and increased fuel ignitibility.  The metal glass fused resistor allows for maximum interference suppression while the ribbed insulator design prevents misfires due to current leakage.
