NGK Laser Platinum Spark Plug Box of 4 (IFR6Z7G)

The dual platinum surfaces on these NGK Laser Platinum spark plugs are laser-welded to ensure a slow wear rate, which helps maintain a stable idle and consistent performance over time. These are designed as an OE equivalent replacement, meaning they meet the same standards as the plugs your Chevrolet Sonic came with from the factory. The pure alumina silicate ceramic insulator is strong and helps with heat transfer, keeping the plug operating at the right temperature. Plus, the trivalent metal plating helps prevent corrosion and seizing, making them easier to remove down the road.

NGK uses a high-grade ceramic insulator with corrugated ribs to prevent flashover, ensuring a strong spark every time. The copper core inside helps remove excess heat, preventing the plug from overheating, while triple seals are used to prevent any leaks. These plugs are a solid option if your vehicle originally came with fine wire iridium alloy plugs, offering improved fuel efficiency and lower emissions compared to worn-out plugs.
