Description
IRIDIUM TWIN TIP
The Iridium TT® Twin-Tip technology delivers far less obstruction to the spark allowing an omni-directional explosion. This minimizes the quenching effect and results in a more effective, more complete combustion. Better combustion means more power and better fuel economy, as fuel is burned more efficiently with each piston firing. The large center and ground electrodes seen on a standard plug increases “quenching” of the explosion, meaning the spark explosion is restricted by the electrodes above and below the gap, allowing it to spread to either side, but not grow with full range.
Built-in, Highly Reliable Resistor
All specification types include an embedded, highly reliable, monolithic resistor to eliminate electoromagnetic noise interference from all kinds of electronic devices.
360° Laser Welding
The iridium tip is mounted with an “All-around Laser Welding” method that insures high reliability even under the most severe driving conditions.
φ0.7mm Needle-Shaped Platinum Ground Electrode
In order to maximally prevent quenching effect, the ground electrode needs to be made as small as possible. Traditional ground electrodes could not be made too small without reducing groundig strength or increasing electrode wear.
However, we’ve managed to attach a fine 0.7mm-diameter platinum electrode using a 360° laser welding technique.
φ0.4mm Ultra-fine Iridium Center Electrode
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.
