NGK V-Power Spark Plug Box of 4 (XR4)

When you're looking to get your engine running smoothly again, replacing worn-out spark plugs is a key step. These NGK V-Power spark plugs are designed to provide reliable performance and improved ignitability, helping your engine start quicker and idle smoother. They're built as an OE equivalent replacement, meaning they're made to fit and function just like the original plugs in a wide variety of vehicles, from classic Chevrolets to older Buicks and Chryslers.

What sets these plugs apart is the unique V-cut in the center electrode. This design helps direct the spark to the edge of the electrode, which helps the spark develop faster and reduces something called 'quenching' – basically, when the spark gets smothered before it can fully ignite the fuel mixture. The plugs also feature a pure alumina silicate ceramic insulator for strength and good heat transfer, and a trivalent metal plating that resists corrosion and seizing, making installation and future removal easier. Plus, the copper core helps manage heat, and triple seals prevent any leaks.
