Description

The Denso 5354 is an Iridium Power spark plug designed to improve firing performance. It features a 0.4mm iridium-tipped, laser-welded fine wire center electrode that requires less voltage for ignition. The spark plug also has a tapered cut U-Groove ground electrode to enhance ignitability and reduce quenching. Machine-rolled threads are incorporated to prevent seizing, and a purified alumina powder insulator offers strength and thermal conductivity, with a five-rib design to prevent flashover.
