NGK Iridium/Platinum Spark Plug Box of 4 (ILTR5E11)

The iridium-tipped center electrode on these NGK spark plugs is six times harder than platinum, offering excellent durability and a stable spark. This makes them a solid choice for many vehicles, providing a reliable replacement for your original plugs. The pure alumina silicate ceramic insulator helps with heat transfer, while the 98 percent pure copper core works to prevent overheating, ensuring consistent performance and easier starts.

NGK builds these plugs with trivalent metal plating, which helps resist corrosion and seizing, making them easier to remove down the road. Many of these plugs also feature a platinum pad on the ground electrode, which helps them wear evenly, especially in modern distributorless ignition systems. They are designed as an OE or equivalent replacement, meaning they fit right and perform as expected for a wide range of vehicles.

This box includes four spark plugs, enough for most 4-cylinder engines or for replacing two plugs on some V8 applications. Always check your vehicle's service manual to confirm the correct plug and the number needed for your specific engine.
