Denso Q20TT Spark Plugs (Set of 4) Review

DENSO TT spark plugs are manufactured using the patented "Super Ignition (SIP)" technology. They provide longer life, reliable starting in all weather conditions, low emissions and better fuel efficiency. The versatility of this type of spark plug makes it possible to cover a large fleet of modern cars with a limited number of articles. In 2010, the serial production of Nickel TT spark plugs began, which is based on an innovative technology that is the result of many years of research and development carried out at the DENSO engineering center in Japan. The research was aimed at solving the dual problem of protecting the environment and achieving high technical efficiency. Nickel TT Spark Plugs are the world''s first spark plugs with fine electrodes without the use of precious metals. Center and ground electrodes with a diameter of 1.5 mm - thinner than standard nickel candles. As a result, DENSO''s Nickel TT spark plugs exhibit a more stable and stable spark and provide a more efficient ignition of the air-fuel mixture. Nickel TT spark plugs outperform standard nickel spark plugs in terms of ignition performance and provide greater fuel efficiency. This is achieved by complete combustion of the mixture in the cylinder, which increases the efficiency of the engine and prolongs its life.
