NGK V-Power Performance Spark Plugs 3951

Affordable Upgrade for Many Trucks. Whether it's for your daily driver or your tried-and-true work truck, NGK's V-power plugs deliver superior performance at an affordable price. The V-power plugs are an inexpensive upgrade and are used and approved by both racers and OE manufacturers to increase performance - why choose a lower quality, lower performance product, that costs the same?

Patented V-Groove Tip. The only spark plug on the market today with a v-groove center electrode, the unique grooved tip design of the NGK V-Power plugs creates a stronger spark and reduces misfires. With a groove cut in the center electrode, parallel to the ground electrode, the spark moves to the edge and is then exposed to more of the combustible air/fuel mixture inside the cylinder. This also reduces the "quenching" effect that occurs under high cylinder pressures, which can cause misfires in high-performance, forced-induction, or nitrous-injected applications. Tested, approved, and recommended by OE manufacturers and racers, this is their plug of choice.

Less Electrical Demand. The unique design of these plugs allows them to use less voltage while still creating a stronger spark than traditional plug designs - and the result is more power and a cleaner burn - at an affordable price.

Long Life. These plugs have a strong reputation for resisting electrical wear and chemical contamination and for their anti-fouling ability - meaning they're an ideal choice for your workhorse vehicle as well as highly modified competition trucks. Regardless of where they're installed, they're a perfect choice for a durable, long-life replacement plug.

OEM Quality. NGK is one of the premier manufacturers of spark plugs worldwide. All NGK plugs are made with a solid copper core, to ensure greater spark and heat transfer. Plus they use a triple gasket sealing process to eliminate the potential for combustion gas to leak back through the shell - superior to other manufacturer's one or two shell design. And their double dipped zinc chromate shell is designed for maximum corrosion and rust resistance.
