NGK IZFR6F-11 CL1 Laser Iridium Plug IZFR6F-11

The NGK IZFR6F11 is a Laser Iridium spark plug designed for performance enthusiasts. It features a fine wire center electrode made of an iridium alloy, known for its high melting point and ability to provide a consistently stable spark. The plug also includes trivalent metal plating for superior anti-corrosion and anti-seizing properties, corrugated ribs to prevent flashover, and a pure alumina silicate ceramic insulator for strength and heat transfer.

The construction also incorporates a copper core for heat removal and triple seals to prevent leakage. This spark plug has a projected center electrode and a standard ground electrode with a taper cut shape. It is a resistor type spark plug with a 5k Ohm resistance value and a heat range of 6. The longevity is rated at 100k miles, and it comes with a 60-day warranty.
