NGK Iridium Spark Plug Set

The NGK ILZKR7G OEM Spark Plug Set is manufactured by NGK specifically for all Alfa Romeo 2.0L Turbo Models, including the Giulia and Stelvio. This set includes four spark plugs, offering a cost-effective alternative to dealer-sourced parts while providing identical quality. These spark plugs are engineered with advanced materials for superior performance and longevity. Key features include a laser-welded Iridium center electrode for high durability and a powerful spark, complemented by a platinum disc welded to the backside of the ground electrode for extended service life. The design incorporates a longer insulator nose to prevent fouling and corrugated ribs on the insulator to inhibit flash-over. A triple gasket seal ensures no combustion gas leakage, contributing to optimal engine performance. Installation benefits include faster starts and quicker acceleration, along with improved fuel economy and lower emissions. The plugs come pre-gapped to a courtesy range of .025"-.026", with a factory recommended gap of .026". Trivalent Metal Plating provides superior resistance to corrosion and seizing. These spark plugs are suitable for a range of driving conditions, from mixed daily commuting to more spirited driving and track use. Applications are confirmed for all Alfa Romeo Giulia 2.0L and all Alfa Romeo Stelvio 2.0L models. Replacement is recommended every 25-30K miles. Eurocompulsion also notes suitability for vehicles equipped with their EURO+DRIVE tuning system.
