NGK Laser Platinum Spark Plug Box of 4 (PLKR7B8E)

If you're looking to keep your 2012-2015 Mercedes-Benz C250 running smoothly, these NGK Laser Platinum spark plugs are a solid choice. They're designed as a direct OE replacement, meaning they'll fit and function just like the original plugs your car came with. The dual platinum surfaces on these plugs help them wear down slowly, which contributes to a stable idle and better fuel efficiency over time compared to standard nickel plugs.

NGK builds these plugs with a pure alumina silicate ceramic insulator that's strong and helps manage heat effectively. You'll also find a trivalent metal plating on the exterior, which helps prevent corrosion and makes them easier to remove down the road. The copper core inside is there to help pull heat away from the firing tip, ensuring reliable starts, and the triple seals are there to prevent any leaks.

This set comes with four plugs, which is exactly what you'll need for your C250. They're a good option if your vehicle originally came with fine wire platinum alloy plugs from the factory.
