Vehicle Specific

Part Number: 3501
Features & Benefits

The DENSO iridium long life plug is fast becoming the standard for today's high-tech engines. Properties of denso's patented iridium alloy have broken through the spark plug technology barrier. Employing a revolutionary new 360° laser-welding process, DENSO has created a spark plug unlike anything on the market today, designed for durability under the most extreme conditions.

  • Using the same laser welding process as the iridium power spark plug, DENSO designed a long life spark plug factory-installed on luxury vehicles.
  • You'll enjoy more horsepower, faster easier starts, less misfires under heavy loads, plus better conservation of fuel at all times.
  • Designed for durability under the most extreme conditions.
  • DENSO's patented iridium alloy is six times harder and eight times stronger than conventional platinum.
