What makes the iridium center electrode special?

The fine wire center electrode is made from an iridium alloy, which has a very high melting point. This allows for a consistently stable spark, which is beneficial for modern, high-performance engines.

Does this set include everything needed for a 4-cylinder engine?

This is a box of four spark plugs, which is typically enough for most 4-cylinder engines. If your vehicle has more cylinders, you will need to purchase additional sets.

What is the benefit of the platinum pad on the ground electrode?

The platinum pad on the ground electrode helps ensure even wear over time, particularly in vehicles that use distributorless ignition systems. This contributes to the longevity of the spark plug.

Product Details

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a solid choice for many vehicles. These plugs are designed to be a direct replacement for your original equipment, offering a good balance of performance and how long they last. They feature a fine wire center electrode made from an iridium alloy, which has a very high melting point and helps ensure a consistent, stable spark. This makes them a good option for modern engines.

The construction includes a pure alumina silicate ceramic insulator for strength and better heat transfer, helping to prevent overheating. For improved resistance to corrosion and seizing, the plugs have a trivalent metal plating. Many of these Laser Iridium plugs also come with a platinum pad on the ground electrode, which helps them wear evenly, especially in distributorless ignition systems. This set includes four spark plugs, enough for most 4-cylinder engines.

These spark plugs fit a range of vehicles, including models like the Jeep Compass, Mazda 626, and BMW 750iL. Always check the fitment guide to confirm compatibility with your specific vehicle.
