Iridium IX Spark Plugs, 4-Pack, for NGK LKAR7BIX-11S

The Iridium IX spark plug (93501 Iridium Ix), designed in a 4-pack specifically for the performance enthusiast, offers extreme ignitability, improved throttle response, and superior anti-fouling capabilities. The 0.6-millimeter laser-welded fine Iridium tip ensures high durability and a consistently stable spark, while the tapered ground electrode minimizes the electrical quenching effect.

The longer insulator nose prevents fouling, and the corrugated ribs on the insulator prevent flashover. Additionally, a triple gasket seal eliminates combustion gas leakage. The Iridium alloy has an extremely high melting point, giving it exceptional durability to heat and electrical wear, making it the perfect choice for today's high-performance engines.

Furthermore, the Trivalent Metal Plating provides superior anti-corrosion and anti-seizing properties, ensuring the spark plugs maintain their optimal performance even in the most demanding conditions. This combination of features makes the NGK LKAR7BIX-11S Iridium IX Spark Plug an exceptional choice for those who demand the best from their high-performance engines.

The fine Iridium tip, with its laser-welded construction, provides a consistently stable spark that is essential for optimizing combustion efficiency and engine performance. The tapered ground electrode minimizes the electrical quenching effect, which can otherwise reduce the spark's effectiveness.

The longer insulator nose and corrugated ribs on the insulator work together to prevent fouling and flashover, ensuring reliable and consistent ignition over the life of the spark plug. The triple gasket seal further enhances the plug's durability by eliminating combustion gas leakage, which can lead to premature wear and failure.

The Iridium alloy used in the Iridium IX spark plug is renowned for its exceptional heat and electrical resistance, making it an ideal choice for high-performance engines that operate under demanding conditions. This durability translates to a longer lifespan for the spark plugs, reducing the need for frequent replacements and ensuring consistent engine performance over time.

Finally, the Trivalent Metal Plating provides superior anti-corrosion and anti-seizing properties, protecting the spark plugs from the harsh environments often encountered in high-performance applications. This feature helps maintain the plugs' optimal performance and ease of installation, even in the most challenging conditions.
