Superior Performance and Acceleration
Extreme Long Life
The spark plug center electrode tip and ground electrode are the areas where most of the wear and tear happens. HELLA Iridium Plus offers superb durability at both the center electrode tip with an iridium tip and a platinum pad on the ground electrode.
Iridium is 6 times harder, 8 times stronger, and has a melting point 700 degrees higher than platinum. Advancement in precision laser technology has enabled laser welding of iridium material to create a uniformly precision-cut tip. Put that into a harsh engine cylinder environment and this translates into a spark plug that lasts much longer than any other plug types (nickel, yttrium and platinum).
The super fine 0.6mm center electrode tip reduces the voltage requirements and allows a focused, concentrated spark ignition. This in turn improves ignitability, offers faster response, faster acceleration and better fuel economy.
