Product Details
This is a box of four NGK Iridium Long Life spark plugs, part number 4477. These are designed to be a direct replacement for your vehicle's original spark plugs, offering a good combination of performance and how long they last. They fit a wide range of vehicles, including models like the Ford F-150, Ford Focus, and Jaguar X-Type.
The center electrode uses an iridium alloy, which is a very hard material that holds up well over time, providing a consistent spark. The pure alumina ceramic insulator helps manage heat, and the trivalent metal plating on the outside helps prevent corrosion and makes them easier to remove later. Most of these plugs also have a platinum pad on the ground electrode to help them wear evenly, especially in modern ignition systems.
These plugs are a solid option if your vehicle originally came with fine wire iridium or platinum plugs. The copper core inside helps pull heat away from the firing tip, and triple seals are used to make sure there are no leaks.
