4 x NGK ILKAR7A7 Iridium Spark Plugs
NGK ILKAR7A7 is equivalent to ILKAR7G9 Laser Iridium Spark Plugs are the best Original Equipment Iridium spark plug available and are an upgraded Iridium spark plug for the 2ZR-FE engine used in Lotus models from 2011.
One of the world’s hardest metals, the precious metal iridium starts melting at a temperature of 2450°C and is therefore very resistant to spark erosion.
Ideal for the performance enthusiast Iridium IX offers extreme ignitability, improved throttle response and superior anti fouling.
Lasers are used to pinpoint precision welds, reducing excess debris; this decreases the required voltage to bridge the spark gap.
The smallest tip diameter available Iridium spark plugs provide superior ignitability and extremely long service life.
An iridium disc is welded on the centre electrode and a platinum disc is welded on the ground electrode, reducing the wear rate of both surfaces and ensuring great durability and long life.
Trivalent metal plating for superior anti-corrosion and anti-seizing
Faster starts and quicker acceleration
Better fuel economy and lower emissions
Iridium/platinum surfaces ensure a slow wear rate, providing stable idle and superior anti-fouling.
Service life is almost doubled compared to standard nickel spark plugs.
