NGK Iridium/Platinum Spark Plug Box of 4 (DILKR8B6)

When it's time to replace the spark plugs on your 2011-2015 Mitsubishi Lancer, you want a set that offers reliable performance and lasts a good long while. These NGK Laser Iridium spark plugs are built to meet or exceed the original equipment specifications for your car, meaning they'll fit right and work as intended.

What makes these plugs stand out is the combination of materials. The center electrode uses an iridium alloy, which has a very high melting point and is six times harder than platinum, giving it excellent durability. The ground electrode features a platinum pad, which helps ensure even wear, especially in modern ignition systems, and contributes to a stable spark. This setup means you get consistent performance and a longer service life compared to standard plugs. Plus, the pure alumina ceramic insulator helps manage heat effectively, and the trivalent metal plating on the body helps prevent corrosion and seizing, making them easier to remove next time around.

This set comes with four plugs, which is exactly what you need for your Lancer. They are designed to provide a strong, stable spark, which helps with smooth engine operation and can contribute to better fuel efficiency.
