NGK V-Power ZFR5N Spark Plugs for Select 1997-2006 Dodge and Jeep (Set of 4)

Fits select 1997-2006 Dodge Dakota, Ram 1500, Viper, and Jeep Cherokee, Grand Cherokee, and Wrangler models.

NGK V-Power spark plugs are engineered to improve ignitability and combustion efficiency over standard nickel plugs in OE applications. The technical centerpiece is the specialized V-cut nickel alloy center electrode. This design directs the spark to the edge of the electrode where it can grow more quickly, resulting in faster flame kernel expansion, more reliable cold starts, and a smoother idle under load.

Built for durability in demanding environments, these plugs feature NGK’s high-grade alumina silicate ceramic insulator for superior dielectric strength and heat transfer. The trivalent metal plating provides a sacrificial layer against corrosion and moisture, ensuring the plugs will not seize in the cylinder head over long service intervals. A pure copper core is utilized to effectively pull heat away from the combustion chamber, preventing pre-ignition and tip overheating.
