NGK spark plugs

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 car manufacturers.

Through the years, our commitment to excellence evolved into an ambitious research and development program. Ceramics, at the core of superior spark plug technology, spawned the creation of NTK Technical Ceramics(www.ntktech.com).
The resulting products, including IC Packages, Piezoelectronics, Ceramic Filters, Fine Ceramics, and Ceramic Cutting Tools set new industry standards.
That same commitment became the driving force in the development of additional lines of products such as NGK Wire Sets, NTK Oxygen Sensors, NTK Knock Sensors and a variety of other NTK sensors (www.ngkntk.co.jp).

It also resulted in a series of world firsts for the industry. These included:
Introduction of copper core spark plugs to the consumer market.
The pioneering development of new ceramics and its revolutionary application to integrated computer circuitry.
Introduction of the "V-Groove" spark plug, which proved ideal for clean-burning, lower-emission engines.
Introduction of Iridium spark plugs for OEM and performance markets.
Continuing environmental and anti-pollution efforts.

With state-of-the-art manufacturing, inventory and distribution facilities in Irvine, California, Sissonville, West Virginia, Chicago, Illinois and ISO 9002/QS-9000/ISO 14001 certification, NGK is dedicated to providing our customers with the finest products and service possible.

NGK Spark Plugs are widely used across all forms of motor sport including Formula 1, Touring Cars, Rally Cars and Motorcycle Racing.

The high compression ratios and engine speeds developed in high performance racing engines require spark plugs, which can withstand overheating and mechanical shock. NGK has a range of plug types capable of withstanding these severe conditions, many using precious metals such as platinum or gold/palladium.

The workhorse, at the heart of smooth-running engines around the world.

For many years NGK Spark Plugs has been firing racing engines throughout the world. NGK Spark Plugs has become an icon in spark plug technology and we pride ourselves in offering racers a high quality product that will help rocket them to victory. We realize race teams push their vehicles to the edge. Knowing this we design every NGK Spark Plug to withstand severe mechanical and thermal shock associated with these high-revving, high-compression race engines. As a result of our superior quality, you'll have confidence knowing you have the World Leader in spark plug technology firing your way to victory.

To withstand the severe conditions that occur in racing engines, NGK Racing Spark Plugs feature electrode materials and configurations as follows:

Electrode materials - Many use precious metals such as platinum or gold/palladium for greater durability and lower voltage requirements.
Electrode configurations - Fine-wire center electrodes provide better sparking and enhanced ignitability. Fine-wire ground electrodes further improve the ignitability of the plug.
Insulator configurations - Special configurations are used for the insulator noses to improve throttle response.
