SPARK PLUG BKR5EIX-11(NGK) / SPARK PLUG

NGK Iridium IX spark plugs are specifically designed for the performance enthusiast. Iridium IX provides outstanding acceleration, high fuel efficiency and durability. NGK Iridium IX plugs offer extreme ignitability and exceptional anti-fouling. Tapered cut ground electrode provides improved starting, idling and throttle response. The Iridium fine wire center electrode's durability is six times harder than platinum. Iridium alloy's extremely high melting point is perfect for today's engines. For even greater performance consider upgrading to an NGK Ruthenium HX plug.

• SOLID COPPER CORE: 98% pure copper core for superior heat dissipation and conductivity
• TAPERED CUT GROUND ELECTRODE: Reduced quenching design for improved ignitability, acceleration, fuel efficiency, and durability
• TRIVALENT METAL PLATING: Offers superior anti-corrosion and anti-seizing properties for ease of installation and removal
• RECOMMENDED USAGE: Ideal for modified or high-performance applications and as an upgrade to OE nickel alloy spark plugs
• SINGLE IRIDIUM TIP: Features a fine wire 0.6 millimeter iridium tip center electrode for high durability and consistent spark
• IRIDIUM ALLOY CENTER ELECTRODE: Iridium's high density and extremely high melting point are perfect for modern high-efficiency engines
