IRIWAY SPARK PLUG
High Heat Rating Plugs for Tuned Engines
PRODUCT DESCRIPTION
NGK IRIWAY Spark Plugs like the NGK Iridium IX, has an Iridium center electrode of 0.6 mm diameter offering performance exceeding traditional spark plugs. The ground electrode of Iridium NGK IRIWAY is tapered cut to provide better flame spread generated by combustion, raising compressions, and ensuring a cleaner burning.
These spark plugs for which alloy has been revised to provide better resistance, were mainly made by NGK in response to direct requests from the competition (Rally, Circuit, Street Race).
