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.
NGK Spark Plugs (USA), Inc. was established in 1966
as a subsidiary of NGK Spark Plug Co, Ltd., of Japan
Its purpose was to establish and develop a market in
the United States for NGK spark plugs and NTK ceramic
In 1976, NGK Spark Plugs Mfg. (USA), Inc. was established
to assemble spark plugs in the United States with construction
of our Irvine, California facility completed in 1981.
In 1984, NGK Spark Plugs Mfg. (USA) merged into NGK
Spark Plugs (USA), Inc. Ultimately, distribution facilities
(1987) and corporate headquarters (1993) were also moved
to the Irvine facility. NGK Spark Plug Mfg (USA), Inc.
was established in 1994 in West Virginia
to produce oxygen sensors. This state of the art facility
is located on a forty-acre campus that includes 113,000
square feet of manufacturing and a 70,000 square foot
warehouse. Initial oxygen sensor production began in
July of 1995 and the warehouse addition in August of
In January 2002, NGK combined NGK Spark Plugs (USA),
Inc and NGK Spark Plug Mfg. (USA), Inc. into NGK Spark
Plugs (USA) Inc., a West Virginia corporation. The corporate
headquarters remain in Irvine, California and the sales
headquarters in Wixom, Michigan.
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.
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.
