NGK Ruthenium HX High Ignitability Spark Plug Set of 4 (LKAR8BHX) - Select Infiniti & Nissan 2008-2020

Fits select 2008-2020 Infiniti G37, Q50, Q60, Q70, and Nissan 370Z and GT-R models.

NGK Ruthenium HX High Ignitability spark plugs represent the pinnacle of modern ignition technology. Engineered for high-efficiency engines, these plugs utilize a patented Ruthenium alloy center electrode that offers superior durability and a higher melting point than traditional platinum or iridium. This LKAR8BHX set provides a more complete fuel burn, resulting in quicker throttle response, a smoother idle, and more reliable cold starts in all conditions.

The specialized DFE (Double Fine Electrode) and PSPE (Projected Square Platinum Electrode) tip designs are derived from OE technology to maximize spark energy. Each plug is constructed with a pure alumina silicate ceramic insulator for better heat transfer and a copper core to assist in heat removal. The trivalent metal plating ensures excellent anti-corrosion and anti-seizing properties, making these the ideal replacement for high-performance modern vehicles.
