What makes the Laser Iridium material special?

The iridium alloy used for the center electrode has an extremely high melting point, which makes it very durable. This allows for a fine wire design that ensures a consistently stable spark, crucial for high-performance and modern engines.

Does this set include everything needed for a tune-up?

This is a box of four spark plugs, which is the correct quantity for many vehicles. You will need to check your vehicle's specific requirements to confirm if four plugs are sufficient for a complete tune-up.

How does the platinum pad on the ground electrode help?

The raised platinum pad on the ground electrode helps ensure even wear over time, especially in distributorless ignition systems. This contributes to improved and consistent spark performance throughout the plug's lifespan.

Product Details

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example of that. These are designed as direct replacements for your vehicle's original plugs, offering a great 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 provides a stable spark, even in today's high-tech engines. This design helps ensure consistent starts and reliable ignition.

The construction of these NGK plugs includes a pure alumina silicate ceramic insulator that's strong and transfers heat well, helping to prevent overheating. For added protection against corrosion and seizing, they have a trivalent metal plating. The ground electrode also has a platinum pad, which helps it wear evenly in distributorless ignition systems and further improves spark performance. These plugs are built to last, with the iridium center electrode offering durability six times longer than platinum.

This set includes four spark plugs, which is what many vehicles need for a complete tune-up. They are a solid option for a wide range of vehicles, including models like the Jaguar F-Type, Land Rover Range Rover, and many others. The copper core inside helps manage heat, and triple seals are used to prevent any leaks.
