Introducing the ultimate evolution in spark plug technology and performance. Superior to Platinum, NGK Iridium spark plugs benefit from their unique patented design which features:
- A Super Fine Centre electrode (0.6mm), reducing voltage requirements, minimizing flame quenching and allowing for a stronger spark.
- New Iridium material with superior anti-oxidation, anti-corrosion and extremely high melting point characteristics.
- Unique 2 stepped centre electrode - a secondary micro discharge burns off carbon deposits as they form.
- Minimized gap growth between electrodes, giving longer life.
- Tapered Cut Ground Electrode ensures an excellent flame spread and improved vibration resistance.
It is the combination of these designs in NGK’s Iridium spark plugs that allows your engine to run more efficiently, producing cleaner exhaust emissions and more power though better ignitability.
