Niterra 94582 ZFR6K-11 V-Power Copper Spark Plug

The Niterra 94582 (ZFR6K-11) V-Power spark plug delivers reliable ignition performance with advanced copper core technology. This OE-quality replacement spark plug features NGK's signature V-cut center electrode design that directs the spark to the edge of the electrode, promoting faster spark development and improved ignitability compared to standard nickel spark plugs.

Key Features:

• V-grooved nickel alloy center electrode places spark closer to air/fuel mixture for faster ignition
• Solid copper core provides superior heat dissipation and conductivity for a broader heat range
• Trivalent metal plating eliminates need for anti-seize and provides superior anti-corrosion properties
• Cold-rolled threads prevent damage to cylinder head during installation
• Pure alumina silicate ceramic insulator delivers superior strength and better heat transfer
• Corrugated ribs prevent flashover for consistent performance
• Triple seals prevent leakage and ensure long-term reliability

Technical Specifications:

• Thread Diameter: 14mm
• Thread Pitch: 1.25mm
• Reach: 19mm (3/4")
• Hex Size: 5/8" (16mm)
• Seat Type: Gasket
• Terminal Type: Solid
• Service Life: Up to 30,000 miles
• Torque Specs: Cast Iron 18-25.3 lb-ft, Aluminum 18-21.6 lb-ft

This spark plug lowers ignition system voltage requirements and enhances fuel economy while reducing emissions. Engineered to OE standards and tested to the highest quality specifications, the Niterra V-Power spark plug is ideal for vehicles equipped with nickel-tipped spark plugs. Note: Spark plugs are pre-gapped for general use but may require adjustment for specific applications.
