Features
DENSO’s patented Nickel TT Spark Plugs feature a nickel centre and a ‘twin’ protruding ground electrode with a slimmer 1.5mm diameter
Highly ignitable technology achieves ignition efficiency closer to DENSO’s premium Iridium ranges, in a design that does not require expensive precious metals
Design that does not require expensive precious metals: in short, improved performance for a lower cost!
Born for cold starts.
Improved ignition performance for a reliable start
With less voltage required to start your engine, this means a quicker, stronger start even in extreme cold weather conditiions
Incorporating an exceptionally fine centre electrode - 1.5mm compared to a standard size of 2.5mm - the spark produced is much stronger, especially in lower temperatures, producing better ignition performance
Benefits
Reducing emissions
Improved Ignitability leads to combustion fluctuation, resulting in less fuel consumption and significantly reduced CO, CO2 and CH emissions
Intelligent design for improved fuel consumption
TT Spark Plug technology allows for a better combustion leading to a lower fuel consumption, saving money in the long term.
Its excellent ignitability ensures better combustion that can ignite leaner mixtures, resulting in less misfiring than a Nickel Plug
Tests show that when comparing a Nickel Plug with a TT Plug, fuel consumption improved by up to 5%, meaning those regular longer journeys become more economical
Range
The complete TT Spark Plug range is highly consolidated, comprising 15 convenient part numbers that together offer 87% coverage of the top selling European car parc.
Denso, founded in 1949 as Nippon Electrical Equipments Co., Ltd, is one of the leading companies in the world in the field of automotive components manufacturing. A key moment in its history was the separation from Toyota Motor Co., Ltd and its establishment as an independent business. However, the collaboration with Toyota continued even after this, allowing Denso to remain one of Toyota's main suppliers.
From the beginning of its operations, the company aimed to create high-quality products. The strategy of innovation and product improvement was key. Denso engineers developed the world's first spark plugs with a platinum electrode and a ceramic spark plug, 12-point fuel injectors, a generator with a segment conductor or a planetary reducer, and an electrical variable valve timing system driven by the engine. A subsidiary of Denso even created the QR code.
Denso's product range is quite diverse and covers many aspects of the automotive industry. These include components for Common Rail fuel systems, diesel pumps, sensors and valves, spark and glow plugs, ignition coils, parts for air conditioning and engine cooling systems, fuel and cabin filters, starters and generators, as well as windshield wipers. The company's products are available for passenger and commercial vehicles, buses, and other transportation vehicles.
Denso continues to be an important player in the automotive industry, focusing on innovation, quality, and global development.
