What NGK Ceramics does

NGK Ceramics USA is a wholly-owned subsidiary of Japan's NGK Corporation, established in 1988 and headquartered at 119 Mazeppa Rd, Mooresville, North Carolina. The company manufactures ceramic catalyst substrates and related emission-control components for diesel and gasoline-powered vehicles. Its core product is HONEYCERAM®, a honeycomb cordierite ceramic substrate with 0.05 mm walls that provides surface area equivalent to two soccer fields in a unit small enough to be hand-held; this substrate is embedded inside catalytic converters during vehicle assembly. The portfolio is broadened by Large-Size HONEYCERAM® (LSH) for heavy-duty diesel equipment, Diesel Particulate Filters (DPFs) using cordierite or silicon carbide, Gasoline Particulate Filters (GPFs) for direct-injection engines, and NOx sensors based on proprietary zirconia (ZrO2) thick-film technology marketed as the world's first such sensors suitable for direct insertion into high-temperature exhaust streams with on-board diagnostic compatibility.

The business operates as a tier-1 OEM supplier with no retail or aftermarket channel. Direct hardware sales flow from NGK Ceramics USA to enterprise automotive manufacturers including General Motors, Ford, and Caterpillar, with the Mooresville facility having undergone 16 expansions since 1988 to serve North American and global demand. The parent company operates additional HONEYCERAM® plants in Japan, Belgium, Poland, Indonesia, South Africa, Mexico, China, and Thailand, with cumulative production exceeding 1 billion HONEYCERAM® units globally. Pricing is unit-based and not publicly disclosed; the company holds ISO 14001, ISO 45001, and IATF (formerly TS) 16949 certifications and has committed to net-zero carbon emissions by 2050 through the Race to Carbon Zero campaign.

Core offering

NGK Ceramics USA manufactures HONEYCERAM® honeycomb ceramic catalyst substrates and complementary emission control products (DPFs, GPFs, NOx sensors) that are sold directly to automotive OEMs for incorporation into catalytic converter systems. The proprietary cordierite ceramic substrates use a honeycomb structure with 0.05mm thin walls to provide extensive surface area for neutralizing particulate matter and NOx from vehicle exhaust.

Product overview

NGK Ceramics USA manufactures ceramic products for diesel and gasoline-powered vehicles. The company operates as a manufacturing facility producing a portfolio of emission control products, with HONEYCERAM® as the core proprietary product. HONEYCERAM® and its variants (Large-Size HONEYCERAM®/LSH) serve as honeycomb catalyst substrates inserted into catalytic converters. The product line is complemented by Diesel Particulate Filters (DPFs), Gasoline Particulate Filters (GPFs), and NOx Sensors that use proprietary zirconia technology. The products work together to neutralize harmful emissions from vehicle exhaust, serving the automotive industry's emission control needs.

Functional benefit

Brands

• HONEYCERAM®: A honeycomb ceramic product used for automobile catalytic converters. It is a powerful unit that has a surface area the size of two soccer fields due to its honeycomb structure design. Made using cordierite ceramics, it demonstrates outstanding performance unimpaired by high temperature and sudden temperature changes accompanying vehicle exhaust.
• Large-Size HONEYCERAM® (LSH)
• Diesel Particulate Filters (DPFs) / Gasoline Particulate Filters (GPFs)
• NOx Sensors

Products and services

• HONEYCERAM® Honeycomb ceramic catalyst substrate used in catalytic converters to neutralize harmful substances in vehicle exhaust. Features a honeycomb structure design with surface area equivalent to two soccer fields within a hand-sized unit, walls only 0.05 mm thick, and is made from cordierite ceramics with outstanding performance at high temperatures and during sudden temperature changes. Used by automotive OEMs including GM and Ford in passenger vehicle production.
• Large-Size HONEYCERAM® (LSH) Large-format honeycomb ceramic catalytic converter insert specifically designed for large diesel vehicles and equipment. Uses the same honeycomb technology as standard HONEYCERAM® and features a catalyst that removes particulate matter (PM) and nitrogen oxide (NOx) from diesel exhaust emissions. Used by commercial vehicle OEMs such as Caterpillar for trucks, buses, and construction machinery.
• Diesel Particulate Filters (DPFs) Filters that eliminate particulate matter from exhaust gas emitted from diesel automobiles. Lightweight cordierite filters are used in trucks, buses, and construction machinery; heat-resistant silicon carbide filters are used in passenger cars. Designed for OEM integration into diesel vehicle exhaust aftertreatment systems.
• Gasoline Particulate Filters (GPFs) Dedicated filter for gasoline direct-injection engines that removes particulate matter from exhaust emissions. Produced using heat-resistant ceramic materials engineered for gasoline engine exhaust conditions and supplied to automotive OEMs.
• NOx Sensors World-first sensors using zirconia (ZrO2) thick film technology. Can be inserted directly into high-temperature exhaust gas to collect precise measurements of NOx concentration over extended periods. Features digital communication ideal for on-board exhaust gas diagnostic (OBD) systems. Sold to automotive OEMs for integration into vehicle emissions monitoring architectures.
