Features & Benefits

The new Bosch Iridium: the most technologically advanced spark plug. Unlike other iridium spark plugs, Bosch Iridium is the only spark plug that combines a 360 degree continuous laser-welded iridium center electrode with a laser-welded iridium-platinum inlay on the ground electrode to provide unmatched quality and OE long life performance.

  • Ultra fine wire iridium center electrode provides exceptional ignitability
  • 360 degree continuous laser welded center electrode provides unmatched resistance to thermal shock that can occur in today's high performance engines
  • Bosch exclusive tapered laser-welded iridium-platinum alloy tipped ground electrode provides more area for flame growth and increased durability
  • Nickel plated housing provides superior resistance to corrosion and seizing
