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.

For over 100 years Champion has been developing and manufacturing spark plugs. The Champion copper plus spark plug was introduced in 1982. It provides dependable performance and longer life on a daily basis to its owners.

Champion’s copper core center electrode allows for accurate control of heat range, optimizing performance and longevity. In addition to those benefits, copper plus also provides the best corrosion protection in the industry and eliminates the need for any use of anti-seize compound altogether with its ultraseal shell.

Champion copper plus, delivering dependable proven performance since 1907.

Laser Iridium Compared to Standard Spark plugs, NGK Laser Iridium provides a superior fuel burn combined with a longer service life. With 6. 5 on the ‘Mohs’ hardness scale, Iridium is the second-densest element to exist (after Osmium), yet it’s also the most corrosion-resistant metal (even at temperatures as high as 2000? C ).

Thanks to Iridium’s excellent electrical conductivity properties, it’s the perfect metal element to include in the manufacture of premium spark plugs. The laser welded platinum disc on the ground electrode provides extra durability, once again improving service life and bringing the wear rate down to a minimum.

With both electrodes working in harmony together, your engine will have a more stable idle with superior anti-fouling, improved fuel efficiency and lower emissions. Another great feature is that the ground electrode is also taper cut, in simple terms, this is done to reduce as much obstruction as possible to the flame expansion (this reduces quenching) as it starts to burn from the electrode tips.

This allows for a more complete, efficient burn which in turn increases MPG. Features Laser welded Iridium centre electrode tip Laser welded Platinum disc on the ground electrode Trivalent metal plating for superior anti-corrosion and anti-seizing properties Faster starts and smoother acceleration Superior anti-fouling Lower required spark voltage, great for those colder mornings Tapered ground electrode improves flame expansion from the initial spark Better fuel economy and lower emissions Factory fitted equipment in many of today’s vehicles (OEM Approved Design) Outstanding quality as you come to expect from NGK.

Proven track record and used in millions of vehicles around the world.
