NGK Spark Plugs, Glow Plugs and Wire Kits

When it comes to spark plugs, NGK is the World Leader. Makers of spark plugs for virtually every automotive, motorcycle, marine and small engine application, NGK dominates.

Starting with a single product in 1936, NGK's extraordinary growth can be attributed to a philosophy of manufacturing the product where it is going to be used. In fact, a substantial number of NGK Spark Plugs and oxygen sensors sold in the United States are made right here in America. One of the benefits of this approach is the ability to work closely with manufacturers in developing products tailored specifically to their needs. The most tangible manifestations of the success of this philosophy have been the construction of fourteen factories in eight nations throughout the world, as well as NGK Spark Plugs being specified as original equipment by the majority of the world's auto manufacturers.

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 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 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

NGK spark plug wire sets are manufactured with the finest materials and quality construction for excellent noise supprsion 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.

NGK Glow Plugs

NGK manufactures all types of glow plugs featuring the latest in technology for diesel applications.

Worldwide restrictions on automotive exhaust gas emission and the promotion of low pollution vehicles are a reflection of our awareness of the need to protect our environment.

Not surprisingly, manufacturers of diesel-powered vehicles are hard at work developing new technology designed to meet increasing restriction on exhaust emissions.

Although glow plugs were originally developed as a method for improving the starting performance of diesel engines, technology has developed to the point where glow plugs also contribute to the reduction of exhaust gas emissions.
