- - Denso Iridium TT Series
- - 0.4mm Ultra-Fine Iridium Center Electrode
Set of 8 Denso Iridium TT Spark Plugs
The Finest TT Plug With Improved Acceleration, Economical and long lasting!0.4mm Iridium Center Electrode and 0.7mm Platinum Needle Achieve High Performance and Durability!
FeaturesBuilt-in, Highly Reliable Resistor - All specification types include an embedded, highly reliable, monolithic resistor to eliminate electromagnetic noise interference from all kinds of electronic devices.
All-around 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.
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. The smaller the electrode the more concentrated the electric potential at the tip of the electrode and the stronger the electric field that affects required voltage and the lower the required voltage. As a result, combustion is good for all types of driving, the engine starts easily, and acceleration improves.
