What makes the iridium center electrode special?

The iridium alloy has an extremely high melting point, which makes the center electrode very durable. This allows for a fine wire design that helps maintain a consistently stable spark, improving performance and longevity.

Do these spark plugs come with everything needed for installation?

This product includes a box of four NGK Laser Iridium spark plugs. It is recommended to refer to your vehicle's service manual for specific installation procedures and any additional hardware or tools that may be required.

How do the trivalent metal plating and platinum pad help?

The trivalent metal plating provides superior resistance to corrosion and seizing, making removal easier. The platinum pad on the ground electrode helps ensure even wear, especially in vehicles with distributorless ignition systems.

Product Details

The iridium alloy in the center electrode has an extremely high melting point, making these NGK Laser Iridium spark plugs a solid choice for today's high-tech engines. These are actual OE replacement plugs, meaning they're built to the same standards as what came on your vehicle from the factory. They fit a range of vehicles, including models like the Audi Q7, Volkswagen Passat, and Porsche Cayenne.

The fine wire center electrode is key here, as it helps maintain a consistently stable spark. NGK also uses a pure alumina silicate ceramic insulator, which offers superior strength and helps with heat transfer. For added durability and to prevent seizing, the plugs feature trivalent metal plating. Most of these plugs also include a platinum pad on the ground electrode, which helps them wear evenly in distributorless ignition systems.

These plugs come in a box of four, and the copper core helps remove heat, contributing to reliable starts. The triple seals are there to prevent any leaks. If your vehicle originally came with fine wire iridium alloy plugs, these are a direct replacement.
