NGK 6510 LTR7IX-11 Iridium IX Gen 5 LT Spark Plug

NGK Iridium IX Spark Plugs (LTR7IX-11) – Gen 5 LT Engines

Optimized for the performance enthusiast, the NGK LTR7IX-11 (Stock No. 6510) is the go-to ignition upgrade for high-performance GM LT-series engines. These plugs are engineered to provide a more stable spark and superior durability under the extreme conditions found in modern high-tech engines.

Performance Features

• 0.6mm Fine-Wire Iridium Tip: The ultra-fine center electrode reduces the voltage requirement for a spark, resulting in faster starts, smoother idling, and improved throttle response.

• High-Temp Resistance: Iridium alloy has an extremely high melting point, ensuring consistent performance in high-compression or forced-induction environments.

• Trivalent Metal Plating: Provides superior anti-corrosion and anti-seizing properties, protecting your cylinder heads and making future plug changes easier.

• Flashover Protection: Corrugated ribs prevent electrical leakage (flashover), ensuring the spark occurs only at the electrode tip.

• Maximum Heat Dissipation: A pure alumina silicate ceramic insulator and a solid copper core work together to pull heat away from the combustion chamber quickly.

• Gas-Tight Seal: Specialized triple seals prevent combustion gas leakage, maintaining engine compression and peak power.

Technical Specifications

Tech Note: While these plugs come pre-gapped at .044", always verify the gap for your specific build requirements, especially in forced induction or nitrous applications.
