![]() The standard plugs are already a performance or enhanced design.There is no close match for your standard spark plug, it isn't worth compromising plug design purely to use an Iridium plug type.The engine has a large cylinder capacity and a large number of cylinders.The standard spark plug you are replacing is a basic copper plug (the Iridium plug will then be a more significant upgrade).There is a very close Iridium spark plug match for your standard spark plug (i.e.The vast majority of vehicles/engines will benefit from replacing a standard spark plug with an Iridium spark plug. WILL AN IRIDIUM SPARK PLUG BE BENEFICIAL FOR MY PARTICULAR ENGINE? Increased engine power (Don't expect to double your horsepower but a 1 - 3% increase is possible).Increased plug service life (Depending on design, an Iridium plug could last up to ten times the life of a standard plug with little reduction in efficiency over the plug's lifespan).Improved economy (though this depends largely on how much you enjoy the improved throttle response!).This is beneficial in several ways:Ī lower voltage is required, this reduces load on a vehicle's ignition system (less strain = less chance of failure)Ī larger gap can be supported without increasing load on the ignition system (Larger gap = larger spark = more efficient combustion)Ī more precise spark every time, delivered in the correct position and with the correct timing (More efficient combustion)Īssuming a suitable Iridium plug is available, benefits you are most likely to see are: The narrow diameter concentrates the electrical charge and therefore a much lower voltage is required to jump the spark gap. The result is that an Iridium electrode can be manufactured with an extremely small diameter, when compared to a traditional copper or even a platinum tipped electrode, without compromising the useful life of the electrode or spark plug. An Iridium alloy electrode is able to deliver good conductivity and extreme hardness. Pure Iridium is difficult to work with, very brittle and does not have great electrical conductivity hence alloys are used to give the best combination of these properties. Since late in the 20th century Iridium has been used in alloy form as material of choice for construction of Spark plug and industrial igniter electrodes. Other than it's hardness, the main property which makes Iridium attractive as an electrode material for spark plugs is its extremely high melting point (almost 2,500 deg C). The Iridium IX has a 0.6mm fine tipped center electrode and taper-cut ground electrode for more flame expansion and dramatic increase in ignitability fine iridium tip on center electrode that ensures ensures high durability and consistently stable spark the Iridium alloy has extremely high melting point, perfect for today’s high-tech, high-performance engines and trivalent metal plating.Iridium is an extremely hard metallic element, related to platinum, which is thought to occur on earth primarily due to an enormous meteor impact millions of years ago. It offers extreme ignitability, improved throttle response, high fuel efficiency, and superior anti-fouling. Meanwhile, the Iridium IX Spark Plug is designed for performance vehicles. In addition to these, the G-Power can endure extremely high heat. It is equipped with a 0.6mm fine tipped center electrode and trapezoidal electrode to provide more area for flame expansion and dynamic increase in ignitability a fine platinum alloy tip on the center electrode that reduces required voltage a trivalent metal plating that has a superior anti-corrosion and anti-seizing properties. The NGK G-Power Platinum Spark Plug has an improved fuel efficiency, lower emissions, quicker starts and quicker acceleration. recently released two new spark plugs that are meant for individuals who want an affordable, fuel efficient, and can improve a vehicle’s throttle response.
