NGK® 97977 Spark Plug

Product Description

NGK® 97977 Spark Plug

SINGLE IRIDIUM TIP: Fine wire 0.6 millimeter iridium tip center electrode ensures high durability and a consistently stable spark

TRIVALENT METAL PLATING: Delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal

SOLID COPPER CORE: 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges

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 electrodes durability is six times harder than platinum. Iridium alloys extremely high melting point is perfect for todays engines. For even greater performance consider upgrading to an NGK Ruthenium HX plug.

TAPERED CUT GROUND ELECTRODE: Reduced quenching design produces outstanding ignitability, improved acceleration, fuel efficiency and durability

Iridium IX Spark Plug

IRIDIUM ALLOY CENTER ELECTRODE: Iridiums density (6x that of platinum) and extremely high melting point is perfect for modern high efficiency engines

RECOMMENDED USAGE: Modified or high performance applications, or as an upgrade to OE nickel alloy spark plugs
