NGK Spark Plugs & Wire Sets
NGK is the world leader in spark plugs and plug wires for both original equipment manufacturers (OEM) and the aftermarket.
NGK has been producing world class products since 1936 and has dominated the world market by being the OEM supplier for companies such as GM, Chrysler, Ford, Toyota, Honda (automobile and powersports), Suzuki and BMW. NGK works closely with these companies to design parts that meet each OEM’s specific needs. The company’s growth and ability to work closely with manufacturers in developing products tailored to their needs is attributed to NGK’s global presence. NGK USA is headquartered in Wixom, Mich. and boasts 14 factories in eight nations. The company also has manufacturing, inventory and distribution facilities in California, West Virginia and Illinois.
NGK Iridium IX Spark Plugs
NGK Iridium IX spark plugs provide unsurpassed performance in auto/light truck and powersports applications. The iridium alloy electrode is extremely durable to heat, corrosion and electrical wear. The fine wire electrode reduces the amount of energy required to create a spark while providing increased ignition efficiency and superior ignitability. The center electrode of Iridium IX spark plugs has an extra anti-fouling mechanism. A thermo edge between the center electrode and the insulator nose provides a gap for a secondary micro-discharge to jump and initiate a self-cleaning process.
NGK V-Power Spark Plugs
NGK V-Power spark plugs offer higher performance in auto/light truck applications than the standard plug. The V-Power electrode lowers ignition system voltage requirements and provides better protection against fouling, greater ignitability and improved performance over conventional spark plugs.
NGK Standard Spark Plugs
NGK Standard spark plugs provide excellent service for many applications, including auto/light truck, powersports and small engines. They feature a triple gasket sealing process that virtually eliminates gas leakage past the shell. Other manufacturers use a one- or two-step sealing process. NGK Standard spark plug insulators are made from 99% pure alumina silicate, allowing for longer insulator noses for reduced fouling. NGK Standard plugs feature a solid copper core that provides superior heat dissipation and conductivity. Their resistors are produced with a glass and carbon mixture, which is fired to ensure superior performance and durability. Some manufacturers use inserts that break. NGK Standard plugs also have corrugated ribs to prevent flash over and cold rolled threads to prevent damage to the cylinder head.
NGK Commercial Spark Plugs
NGK Commercial series spark plugs are specifically designed for commercial and other small engine applications, including lawn equipment, trimmers, pumps and generators. Their easy starting, anti-fouling design helps deliver longer life in heavy-duty and commercial applications.
NGK Spark Plug Wire Sets (Discontinued)
NGK spark plug wire sets are manufactured with the finest materials and quality construction for excellent noise suppression and superior conductivity. They offer exact OEM fit, form and function and the quality of their construction is unsurpassed.
NGK plug wires use a stainless steel terminal with three serrated crimps, while the competition uses a galvanized steel terminal with only one crimp. NGK plug wires have a stainless steel “C” clip with a corrosion resistant chromate retainer, providing improved durability and ensuring a lasting connection. NGK wire sets incorporate EPDM rubber or silicone jacket material. These two materials have the highest temperature ratings and insulation properties. They also use high-temperature silicone adhesive to bond the boots to the wire, preventing moisture intrusion and securing the components together.
