NGK Iridium/Platinum Spark Plug Box of 4 (ILKR7B8)

If you're looking to replace the spark plugs on your 2008-2015 Smart Fortwo, these NGK Laser Iridium plugs are a solid option. They're built to be an exact OE replacement, meaning they'll fit right in and perform as the original equipment did, but with some notable improvements for durability and spark stability.

What makes these stand out is the iridium-tipped center electrode, which is significantly harder than platinum and helps ensure a consistent, strong spark over a longer period. The pure alumina ceramic insulator helps manage heat, preventing the plug from getting too hot, while the 98 percent pure copper core also aids in heat removal. For vehicles with distributorless ignition systems, like many modern cars, the platinum pad on the ground electrode helps promote even wear, extending their life even further. The trivalent metal plating on the outside also helps prevent corrosion and makes them easier to remove down the road.

This set comes with four plugs, which is exactly what you'll need for your Smart Fortwo. NGK is a well-known name in ignition components, and these plugs are designed to offer a good balance of performance and longevity for your daily driver.
