Overview

The Nismo Iridium Spark Plugs are high-performance ignition components engineered by NGK with an ISO heat range of 8. Featuring a 0.6mm iridium electrode, these spark plugs are designed to improve ignition performance and combustion efficiency for increased power and engine response.

The inclusion of a thermo edge at the top of the insulator helps control carbon deposition, which improves reliability and promotes consistent idling. Each set includes two spark plugs.
Show original supplier description
The Nismo Iridium Spark Plugs are specialized ignition upgrades manufactured by NGK, featuring an iridium alloy construction with a precise 0.6mm electrode diameter. The advanced thermo edge design on the insulator proactively manages carbon buildup, effectively mitigating the risk of firing issues and maintaining stable idle quality over the service life of the plug. These spark plugs feature an ISO heat range of 8. They are sold as a set of two. Please note that these plugs are explicitly not compatible with direct fuel injection engines, including the QR20DD, QR25DD, VQ25DD, VQ30DD, and VK45DD engine series. Buyers are encouraged to verify engine-specific compatibility requirements, as fitment guidance is provided for JDM-spec vehicles.
