NGK 2761 PFR5G-13E Laser Platinum Spark Plug 14mm 5/8 Hex Heat Range 5

The NGK 2761 Laser Platinum spark plug (PFR5G-13E) is an OE-quality platinum-tipped replacement plug. It is built for stable idle, strong anti-fouling performance and long service life compared with conventional nickel spark plugs. NGK is a leading OE spark plug supplier, and this plug is engineered for original equipment applications.

Key Features:

• Laser-welded platinum center electrode with a fine wire design for consistent ignitability and longer wear
• Platinum tip on the ground electrode to reduce gap erosion and wear evenly
• 98% pure copper core for heat dissipation and conductivity across a wide heat range
• High-grade alumina ceramic insulator for strength and good heat transfer
• Trivalent metal plating for corrosion and anti-seize protection, which makes installation and removal easier
• Corrugated insulator ribs to help prevent flashover, plus triple seals to prevent leakage
• Built-in resistor (10k ohm) to help suppress radio-frequency interference
