NGK LTR7IX-11/01 6510 Iridium IX Spark Plug

The NGK LTR7IX-11 6510 Iridium IX Spark Plug is meticulously engineered to provide superior ignition performance for a variety of automotive applications. Featuring a fine wire iridium center electrode, this spark plug offers exceptional ignitability, improved fuel efficiency, and reduced emissions. The iridium alloy center electrode is six times harder than platinum, ensuring high durability and a consistently stable spark.

The spark plug’s design includes a tapered ground electrode, which reduces quenching and results in better combustion and improved throttle response. The solid copper core and high-grade alumina silicate ceramic insulator provide excellent heat dissipation and dielectric strength. Additionally, the trivalent metal plating delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal.
