About these plugs
NGK Iridium IX plugs are made for performance engines and are a common upgrade from original-equipment nickel plugs. A fine 0.6 mm iridium center electrode gives a stable, consistent spark and wears far more slowly than nickel.
- Fine-wire iridium tip: iridium is much denser than platinum and has a very high melting point, so the 0.6 mm tip holds its shape for a long service life.
- Tapered-cut ground electrode: takes less energy from the spark, for easier starts, a smoother idle and quicker throttle response.
- 98% copper core: pulls heat away from the tip and gives the plug a wide working heat range.
- Trivalent metal plating: resists corrosion and seizing, so the plugs thread in and come out cleanly.
- Where they fit best: modified and high-performance engines, including turbocharged and supercharged ones, or as a step up from standard plugs.
The plugs come gapped at 0.8 mm (0.031 in). Check the gap your engine calls for before installing.
