About this part

Product Details

NGK Laser Platinum spark plugs are a solid choice when you need reliable ignition for your vehicle. These are built with a dual platinum surface on both the center and ground electrodes, which helps them last much longer than standard nickel plugs. This design also contributes to a more stable idle and can help improve fuel efficiency and lower emissions.

The insulator is made from pure alumina silicate ceramic, which is strong and transfers heat well, while the copper core inside helps prevent the plug from overheating. You'll also find a trivalent metal plating on the outside, giving it good resistance to corrosion and making it easier to remove later on. These are a great option if your car originally came with fine wire platinum alloy spark plugs.

This set includes four spark plugs, which is the correct amount for most 4-cylinder engines. They are designed to be a direct replacement for your original equipment spark plugs.
