Fitment. Whether you're putting a fresh set of plugs in a C6, a C4, or a C4 ZR-1, these V-Power plugs from NGK are a direct fit. These 3951 plugs fit the following years and models: 92-95 C4 (LT-1), 93-95 C4 ZR-1 (LT-5), or 07 C6 (LS2).
Patented V-Groove Tip. NGK's V-Power plugs feature a unique
grooved tip design cut in the center electrode parallel to the ground electrode.
The design improves ignitability by moving the spark to the edge of the
electrode, and exposing it to more of the combustible air/fuel mixture. And it's
not only good on paper, it's a design that's been tested and approved by both OE
manufacturers and racers.
Quicker Spark, Less Voltage. With the V-power design, no heat is
absorbed by the electrode itself, so the flame kernel expands quickly and
efficiently creating a strong spark. And these plugs require less voltage than
traditionally designed plugs - and the result is more power and great
performance from an affordable plug.
Long Life. NGK's V-power plugs have developed a great reputation
for being durable against electrical and chemical wear and contamination -
making them an excellent choice when a long-life replacement plug is in order.
They also have strong anti-fouling characteristics, making them a solid choice
for any application.
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.
