NGK Iridium/Platinum Spark Plug Box of 4 (IZKR7B)

The center electrode on these NGK spark plugs is tipped with an iridium alloy, which has a melting point six times harder than platinum. This means it holds up better over time, giving you a more consistent spark for longer. They're built as an OE replacement, so they're designed to fit right and perform like the original plugs in a wide range of vehicles, including models like the Audi A3 Quattro, Porsche Cayenne, and Volkswagen Touareg.

NGK uses a pure alumina silicate ceramic insulator for strength and better heat transfer, helping to prevent overheating. The pure copper core also aids in removing heat from the plug. For vehicles with distributorless ignition systems, you'll find a platinum pad on the ground electrode, which helps ensure even wear. Plus, the trivalent metal plating on the body helps resist corrosion and makes them easier to remove later on.

This set comes with four plugs, which is what most common engines need. They're a solid option if your vehicle originally came with fine wire iridium plugs and you're looking for a reliable replacement that offers improved longevity.
