DENSO IRIDIUM IK31 SPARK PLUG
DENSOs Iridium Long Life spark plugs are fast becoming the standard for todays high performance engines.
The properties of DENSOs patented Iridium alloy have broken through the spark plug technology barrier with revolutionary new 360 laser welding technology that has made them like no other in the market today.
We use and highly recommend Denso Iridium plugs.
- 0.4mm Iridium tipped laser welded Fine Wire center electrode reduces required voltage and improves firing performance.
- Tapered cut U-Groove ground electrode increases ignitability and decreases quenching
- Machine roller threads prevent seizing or cross threading during installation and removal
- 100% pre-fired to assure the highest quality possible
- Purified alumina powder Insulator provides exceptional strength and thermal conductivity
- Five rib insulator prevents Flashover
- Copper-glass seal bonds Center Electrode and insulator for a gas-tight seal
