Tt Plugs

For over 60 years, DENSO has been leading the way bringing new technology to drivers around the world. DENSO revolutionized spark plug design with our U-Groove spark plugs, and DENSO pioneered Iridium technology for spark plugs. The end result is a full line of spark plugs designed for a wide range of applications. Iridium and platinum technologies combine with our patented 360 Degree laser welding process to create a plug with a lifetime over 100,000 Miles. Improved Ignitability DENSO's TT or "Twin-Ti p" technology promotes the largest spark energy concentration and explosion, which translates into improved acceleration and economy. The Iridium TT features the world's smallest 0.4 Millimeter Iridium center electrode and 0.7 Millimeter needle tip ground electrode, which minimizes spark interference and thus maximizes ignitability. The result is the best performance you can buy, with better power, Torque, and fuel economy than any other spark plug.
