NGK LKAR7BIX-11S Iridium IX spark plug, 4 Pack, has a long insulator nose to prevent fouling. The insulator’s tapered ground electrode reduces the risk of electrical short circuits and improves fuel economy. It also offers an anti-fouling coating on the insulator. This makes it ideal for high performance engines. Notably, Iridium IX is used in Formula One racing since its launch in 2015.
Longer insulator nose prevents fouling, and the triple gasket seal eliminates combustion gas leakage. The NGK Spark Plug LTR5BI-13 90083 packs of 4 spark plugs are made from nickel-tin alloy with copper core for superior anti-corrosion and anti-seism properties. It has been tested to ensure that it does not cause any damage to the engine or fuel supply. The spark plug’s weight is less than 1.2 kg per cylinder. Notably, this is the first
E3.81 spark plug, which has been designed with a diamond-shaped ground electrode, is used to improve fuel efficiency and reduce emissions. The electrode’s design allows the engine to run at higher temperatures without damaging the internal components. It also helps in reducing carbon monoxide emissions by up to 5%. This comes after an RTI test found that the spark plug was not working properly due to improper installation. Notably, the diesel engine uses more fuel than petrol.
