NGK SILMAR8A9S Spark Plug 2‑Pack (#90992) – Fits Honda Talon 1000R / 1000X & Africa Twin Models

OVERVIEW

The NGK SILMAR8A9S spark plug set restores reliable ignition and consistent engine performance for routine maintenance on select Honda powersports models. This genuine NGK two-pack provides durable copper-core construction with a pure alumina silicate ceramic insulator optimized for demanding riding conditions. Designed as a direct replacement for units like the Honda Talon 1000R, these plugs ensure stable combustion and improved thermal management during operation.

ENGINEERING & PERFORMANCE

A copper core enhances heat removal while the trivalent metal plating resists corrosion and seizing, extending service intervals between replacements. Corrugated ribs prevent flashover, and the triple-seal construction eliminates gas leakage to maintain secure compression. These engineering traits support dependable cold starts, reduce firing end fouling, and deliver optimum performance under heavy loads.
