Product Details

Iridium Long-Life Spark Plug by Denso®. Iridium Long Life Plug - Patented Iridium Alloy Plug (90% Ir) with Platinum Ground Strap. Denso's patented Iridium alloy is more durable than even Platinum, allowing the center electrode to be shrunk to only 0.7 mm in diameter. This produces a dramatic improvement in ignitability and spark plug life.

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, Denso's patented Iridium alloy is six times harder and eight times stronger than conventional Platinum and can handle temperatures in excess of 4,000°F.
