Description

The Denso 3524 is an iridium long-life spark plug designed for enhanced performance and longevity. It features a 0.7mm iridium-tipped, laser-welded fine wire center electrode and a platinum-tipped fine wire ground electrode. These advanced materials and design minimize spark interference, aiming to improve power, torque, and fuel economy. The spark plug also includes machine-rolled threads to prevent seizing, a purified alumina powder insulator for strength and thermal conductivity, and a five-rib insulator to prevent flashover.
