NGK Ruthenium HX Performance Spark Plug Set (LTR7BHX) - Ford Fiesta ST MK7

These NGK Ruthenium HX Spark Plugs are designed for engines which demand high ignitability. The Projected Square Platinum Electrode (PSPE) design promotes spark energy concentration and ignites a wider range of air-fuel ratios, offering improved performance in rich or lean engine conditions.

Features 0.4mm Ruthenium alloy fine wire center electrode and 0.8mm platinum fine wire ground electrode. The trivalent metal platinum provides superior anti-corrosion & anti-seizing properties, and the corrugated ribs prevent flashover. Also features pure alumina silicate ceramic insulator which provides superior strength and better heat transfer. The copper core aids in heat removal.

Latest technology in spark plugs.
