Genuine Denso Iridium TT Spark Plug - IK20TT / 4702

Spark plugs ignite the air and/or fuel mixture of a spark ignition engine. - Manufacturers part number: IK20TT

• All specification types include an embedded, highly reliable, monolithic resistor to eliminate electoromagnetic noise interference from all kinds of electronic devices.
• 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.
• The iridium tip is mounted with an “All-around Laser Welding” method that insures high reliability even under the most severe driving conditions.
• 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.
