NGK Laser Iridium Spark Plug Box of 4 (IFR6B-K)

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example of that. If you're working on your 2006-2012 Mitsubishi Eclipse, these are the actual OE-equivalent replacements you'll want to consider. They're built to provide a good balance of performance and how long they last, ensuring your engine runs smoothly for miles to come.

What sets these plugs apart is the iridium-tipped center electrode, which is significantly harder than platinum and helps maintain a stable spark. This advanced material has a very high melting point, making it suitable for today's engines. You'll also find a platinum pad on the ground electrode, which helps them wear evenly, especially in distributorless ignition systems. The pure alumina silicate ceramic insulator offers great strength and helps transfer heat away from the plug, while the trivalent metal plating resists corrosion and seizing, making installation and removal easier.

This set includes four spark plugs, enough for most common 4-cylinder or V6 engine configurations. They are designed to be a direct replacement, so they should fit right in without any modifications.
