For a list of all spark plug options, see NME3010-P.

NGK iridium plugs represent the ultimate evolution of spark plug technology and performance. The iridium center electrode is both stronger and harder than platinum. This allows NGK engineers to design an ultra-fine (0.6mm)center electrode reducing the voltage requirement for spark. This allows for a brighter, stronger spark from your existing ignition system. The ground electrode has a tapered cut at the firing end which reduces quenching for better flame core growth and increased ignitability. The combination of fine wire center electrode and tapered cut ground will increase performance, improve acceleration, and fuel efficiency.

Advantages of Iridium spark plug types
Because of the properties of Iridium, the spark plugs centre electrode can be made with a much smaller diameter than with platinum types (0.6mm), Gold or gold palladium and copper/nickel types. This means that spark plugs potential difference is more concentrated and hence less 'spark jump' voltage is required - this can be as much as 5,000 volts less than with standard plug types. Ignition is improved and less strain is placed on the ignition system. Benefits of improved ignition/combustion include better fuel economy, increased power/acceleration and especially better throttle response.

Iridium: 8 times stronger than platinum, 6 times harder, and with a melting point 1200 degrees higher. New laser welding techniques make it possible to make a spark plug with an iridium electrode. The result is a plug that requires less voltage to spark, burns more of the fuel in the cylinder, and can spark at LEANER air/fuel mixtures, resulting in higher horsepower and better gas mileage. Although the plugs are expensive, you don't have to change them as often as garden variety spark plugs. The iridium electrode is extremely resistant to erosion, so it can last MUCH longer than a normal plug. (Longevity will vary by usage, fuel mixture, and other factors.)

Subject to manufactureres warranty.

Iridium IX plug, 14mm, 3/4" reach, 5/8" hex, gasket seat, resistor, ISO length, projected extended tip, fine wire (0.6mm) iridium center electrode, tapered cut ground electrode, .032"gap

Use of anti-sieze compound with proper torque is highly recommended when installing spark plugs.
