NGK G-Power Spark Plug Box of 4 (TR5-1GP)

This product includes a box of four NGK G-Power Platinum spark plugs, part number TR5-1GP. These are a solid option for many vehicles, offering a step up from standard nickel alloy plugs without breaking the bank. They feature a fine wire platinum center electrode, which requires less voltage to fire. This can lead to quicker starts, especially in colder weather, and can also contribute to improved acceleration and better fuel economy compared to older, conventional spark plug designs.

The design includes a trapezoidal cut on the ground electrode, which helps reduce the area where the spark can be quenched, promoting a more complete burn. The insulator is made from pure alumina silicate ceramic, giving it strength and good heat transfer properties to help keep the plug at the right operating temperature. For added durability and to prevent seizing, the metal plating on the outside is a trivalent type, offering good corrosion resistance. Triple seals are also incorporated to prevent any combustion gases from leaking past the plug.

These G-Power plugs are a great choice if you're looking for an economical way to get the benefits of platinum in your ignition system. They fit a range of vehicles, including models like the Ford Escort and Mercury Lynx, and are an excellent upgrade over original equipment nickel alloy plugs.
