It is general question concerning DENSO SPARK PLUG that is often.
 |
I drive a GT-R tuned to 850HP. Would it be okay to install 0.4mm dia. Iridium Power series plugs? |
|
| The DENSO Iridium Series have 0.4mm iridium center electrodes, but because the durability of the iridium alloy developed by DENSO is higher that even platinum, which has in the past been said to be the most durable, it can be said that it's the best plug for tuned engines. Specifically, it has the following advantages: |
| [1] |
Iridium alloy has a melting point and hardness above that of platinum, even turbo, with its high combustion temperature, can be used with confidence. Also, even when used with powerful ignition systems such as MSD and MDI, these plugs are even more reliable than platinum racing plugs. |

The issue for high boost engines is that misfiring that occurs at high revolutions. The fine electrodes of the Iridium series require a lower voltage, allowing the energy generated by the coil to be sparked without losses. It can be said the 0.4mm dia. DENSO Iridium Power series are a strong ally of tuned high-boost turbo systems. |
