NGK Laser Iridium Spark Plug Box of 4 (SILMAR9F9)

NGK is a well-known name for dependable ignition components, and their Laser Iridium spark plugs are a prime example of that reputation. These plugs are built to offer a solid mix of performance and durability, making them a great choice for your vehicle. They are designed as an OE equivalent replacement, meaning they meet the same standards as the original plugs your car came with.

The center electrode on these plugs uses an iridium alloy, which is significantly harder than platinum and can handle the high temperatures found in modern engines. This iridium tip, along with a fine wire design, helps ensure a consistent and stable spark. The insulator is made from pure alumina silicate ceramic, which is strong and helps transfer heat away from the plug effectively. For added protection against corrosion and seizing, the metal plating is trivalent. Plus, the copper core helps manage heat, and triple seals are in place to prevent any leaks.

These spark plugs are sold individually, but are packaged in a box of four, which is convenient if you need a full set for your vehicle.
