Denso Spark Plug - IXEH22TT

IXEH22TT | Twin Tip Plug | Tightneing Torque (Nm): 17 | 1 - Earthed Electrode | Diameter (mm): 12 | Thread Length (mm): 26.5 The Finest Twin Tip plug with improved acceletation, fuel economy and longevity compared to single tip plugs. The quenching effect has been decreased by forming the electrode into a double needle shape. As a result, the flame kernel rapidly develops and the engine’s power is drawn out to its maximum potential. DENSO IRIDIUM TT spark plugs have a φ0.4 mm iridium alloy center electrode and a 0.7 mm needle-type platinum alloy ground electrode. The iridium tip is mounted with an “All-around Laser Welding” method that insures high reliability even under the most severe driving conditions. Using DENSO’s exclusive iridium alloy having a very high melting point, the tip of the center electrode can be shaped very thin and fine, reducing spark voltage requirements and greatly improving ignitability. All specification types include an embedded, highly reliable, monolithic resistor to eliminate electoromagnetic noise interference from all kinds of electronic devices.
