NGK LKAR8BHX 91784 Ruthenium HX Spark Plugs for Nissan R35 GTR

NGK Ruthenium HX spark plugs for the R35 GTR, engineered for modern engines requiring high ignitability. Featuring a Projected Square Platinum Electrode (PSPE) design, these plugs focus spark energy to ignite a broader range of air-fuel ratios, enhancing performance in both rich and lean conditions. Each plug includes a 0.4mm ruthenium alloy fine-wire center electrode and a 0.8mm platinum fine-wire ground electrode. The trivalent metal platinum coating resists corrosion and seizing, while corrugated ribs prevent flashover. A pure alumina silicate ceramic insulator ensures exceptional strength and heat transfer, complemented by a copper core for efficient heat dissipation. 

Sold individually. Price is for one plug, please adjust quantity as needed.
