NGK Laser Iridium Spark Plug Box of 4 (ILFR5T11)

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example of that. These are designed to be a direct replacement for your original equipment, meaning they'll fit right in and perform as expected. If you're looking to replace worn-out spark plugs on your Toyota Camry, Ram 2500, or Scion tC, these are a solid option.

What makes these stand out is the iridium-tipped center electrode, which is significantly harder than platinum and built for a long life. This iridium alloy has a very high melting point, making it well-suited for modern 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 ceramic insulator helps with heat transfer and strength, while the copper core helps prevent overheating. Plus, the trivalent metal plating on the outside helps prevent corrosion and seizing, making them easier to remove next time.

This set comes with four spark plugs, which is what most vehicles need for a complete tune-up. Just remember to check your vehicle's specific requirements to ensure these are the correct plugs for your application.
