| Denso IK27 Iridium set of 6 Denso 27 heat range is NGK heat range 9 Iridium plug, 14mm thread, 19mm reach, 16mm(5/8") hex, gasket seat, ISO height, 0.4mm iridium center electrode, tapered cut U-groove ground, resistor, 0.32" gap |
| Construction of NGK and Denso plugs is similar for the most part, the big difference being Denso's use of a 0.4mm Iridium tipped center electrode - claimed to be the world's smallest production center electrode, where NGK's is 0.6mm. As with NGK Iridium, and indeed most other spark plugs, the narrower the center electrode is, the lower the potential difference (voltage) that is required to jump the gap between center and ground electrodes. It follows that the Denso plug will require an even lower 'spark jump' voltage than the NGK plug. The Denso plug also utilizes a 'u-grooved' ground electrode which is claimed to aid in the production of a 'flame core' which further improves the combustion process |
