What makes iridium spark plugs last longer than platinum ones?

Iridium has a much higher melting point than platinum, making it significantly harder and more resistant to wear. This allows the electrode to maintain its shape for longer, ensuring a consistent spark over the life of the plug.

Do these spark plugs come with anti-seize pre-applied?

While these plugs feature trivalent metal plating for superior anti-corrosion and anti-seizing properties, it's always a good practice to apply a small amount of anti-seize compound to the threads before installation, especially on aluminum cylinder heads. Refer to the manufacturer's installation instructions for specific recommendations.

Product Details

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a great example of that. If you're working on your 2014-2020 Mitsubishi Outlander, these are the plugs designed to go right in and keep your engine running smoothly. They combine high ignitability with the durability you need for everyday driving.

What makes these stand out is the iridium center electrode, which is much harder than platinum and lasts longer. You also get a platinum pad on the ground electrode, which helps ensure even wear, especially in modern ignition systems. The pure alumina ceramic insulator helps manage heat effectively, and the trivalent metal plating on the shell makes them resistant to corrosion and seizing, which is a big help during installation and removal.

These are actual OE replacement plugs, meaning they're built to the same standards as what came from the factory. The copper core inside helps pull heat away from the plug's tip, preventing overheating and ensuring reliable starts. You'll get a box of four, which is exactly what you need for your Outlander.
