NGK Laser Iridium Spark Plug Box of 4 (ILKAR7J7G)

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example. If you're looking to replace the spark plugs on your 2016 or 2017 Smart Fortwo, these are the exact OE equivalent you'd find from the factory. They are built to handle the demands of modern engines, ensuring your car starts reliably and runs smoothly.

What sets these plugs apart is the iridium-tipped center electrode, which is significantly harder than platinum and offers a very stable spark. This fine wire design helps maintain a consistent spark over time, which is crucial for efficient combustion. The pure alumina ceramic insulator helps manage heat, and the copper core further aids in removing excess heat from the plug. For added protection against corrosion and seizing, they feature a trivalent metal plating, making them easier to remove during future maintenance.

These plugs are designed to be a direct replacement, fitting right into your Smart Fortwo without any modifications. They come as a set of four, ready to get your engine running its best.
