- RECOMMENDED USAGE: Modified or high performance applications, or as an upgrade to OE nickel alloy spark plugs
- Trivalent metal plating for superior anti-corrosion and anti-seizing properties
- Outstanding acceleration, high fuel efficiency and durability
- Fine iridium tip ensures durable and consistent spark
The NGK Iridium IX Spark Plugs (Part Number 6988) are engineered for high-performance automotive applications, providing exceptional ignition efficiency and durability. Designed with a tapered cut ground electrode, these plugs deliver improved starting, consistent idling, and responsive throttle performance. The fine iridium tip ensures a durable spark that maintains optimal combustion, contributing to enhanced acceleration and fuel economy. The iridium alloy's high melting point and increased hardness—six times that of platinum—enable these plugs to withstand the demanding conditions of modern engines while resisting fouling and corrosion through trivalent metal plating.
Suitable for a range of vehicles including the 2003 Saab 9-5, 2001 Honda S2000, 2001 Acura Integra, and more, these plugs are ideal for modified or high-performance engines as an upgrade from standard nickel alloy options. NGK's commitment to quality is reflected in the anti-corrosion and anti-seizing properties of the platinum coating, ensuring reliable performance over extended service intervals.
Whether you're enhancing the performance of your vehicle or replacing worn-out spark plugs, the NGK Iridium IX provides outstanding acceleration, high fuel efficiency, and long-lasting durability. Each box contains four plugs, making it convenient for multi-cylinder engine maintenance, and they are compatible with a variety of Honda, Acura, Saab, and Yamaha models. Trust NGK's proven engineering for a reliable spark that keeps your engine running at peak performance.
