Used by over 87% of the world's OEM manufacturers, NGK spark plugs are the leader in quality as well as performance, offering improved fuel economy, quick starts, and longer life. Most NGK passenger car spark plugs are available in V-power or platinum-tip configuration. For cars that are daily drivers with mild performance upgrades, platinum plugs are recommended because they can offer improved fuel economy and longer plug life. For high-performance normally aspirated, or turbocharged race applications, V-power groove plugs are recommended because they offer more overall horsepower (the tradeoff for more horsepower is a slightly shorter average plug life). Depending on your application and driving conditions, both the V-groove and platinum plugs are available in several heat ranges (hotter or colder).
Iridium IX Spark Plugs are the most technologically advanced high performance plugs available. Featuring a 0.6 mm iridium center electrode tip, they offer superior ignitability without sacrificing durability. The tapered ground electrode increases flame kernel expansion, while the superior heat range design is ideally suited to the demands of high performance environments. Specially designed to meet the needs of serious enthusiasts, Iridium IX Spark Plugs offer outstanding acceleration, high fuel efficiency and long life. When you demand the most from your engine, rely on the proven performance of NGK Iridium IX Spark Plugs.
