Description

The Denso 3523 is an iridium long-life spark plug, designed with a 0.7mm iridium-tipped, laser-welded fine wire center electrode and a platinum-tipped ground electrode. It features machine-rolled threads to prevent seizing and cross-threading, and a purified alumina powder insulator for strength and thermal conductivity. This spark plug is 100% pre-fired to ensure quality and includes a five-rib insulator to prevent flashover.
