DENSO IT22 Iridium Power Spark Plug

The DENSO IT22 Iridium Power spark plug features a 0.4mm iridium tipped laser welded fine wire center electrode that reduces required voltage and improves firing performance. With a 0.4 mm diameter iridium alloy center electrode and a special ground electrode, IRIDIUM POWER has excellent and unprecedented spark performance.

Key Features:

• Tapered cut U-Groove ground electrode increases ignitability and decreases quenching
• DENSO patented 360 degree laser welding process: ensuring exceptional quality bond and structural strength with the iridium center electrode
• Machine rolled threads prevent seizing or cross threading during installation and removal
• Purified alumina powder insulator provides exceptional strength and thermal conductivity
• Five rib insulator prevents flashover
• All IRIDIUM POWER plugs include a highly reliable, 5,000 ohm monolithic resistor specification to reduce electromagnetic noise that may affect electronic devices
• 100% pre-fired to assure the highest quality possible

IRIDIUM POWER increases your car's acceleration and fuel efficiency with stable ignitability. The 0.4mm iridium center electrode delivers maximum spark energy while withstanding temperatures in excess of 4,000 degrees Fahrenheit, combining to achieve higher ignitability and require lower spark voltage than ever before, resulting in improved acceleration compared to standard spark plugs.
