Durable

HELLA Energy Spark Plug has a nickel center electrode with copper core that increases the thermal conductivity, offering excellent heat dissipation and ultimately making the spark plugs more durable. Selected part numbers come with resistance center electrode that suppresses interference caused during sparking. ;

Long Life, Better Combustion

HELLA Energy Plus features a nickel alloy ground electrode U-groove design that allows a larger area for the flame kernel enabling more complete combustion leading to better fuel efficiency. Each plug is incorporated with yttrium enhanced center electrode that lasts longer than typical OE plugs. HELLA Energy Plus also comes with resistance added center electrode. For many modern cars with on-board electronic systems and electronic fuel injection, such resistance in the spark plugs greatly suppresses the electromagnetic interference caused during sparking.

Better Performance and Longer Life

HELLA Platinum Spark Plug offers a platinum center electrode tip that offers high durability and long service life. It lasts longer than typical OE plugs including yttrium enhanced plugs.

The fine tip reduces ignition voltage requirement and improves ignitability, giving faster response, faster acceleration and improved fuel economy.

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.
