NGK 92460 LZFR5AIX-11E Iridium IX Spark Plug, 14mm Thread, 26.5mm Reach

The NGK 92460 Iridium IX spark plug (LZFR5AIX-11E) is a performance-grade iridium spark plug. It is made for enthusiasts and for owners upgrading from standard nickel alloy plugs. A fine wire iridium center electrode and a tapered cut ground electrode give strong ignitability, quick throttle response, good fuel efficiency and long service life.

Key Features:

• Single iridium tip: 0.6 mm fine wire iridium center electrode for durability and a consistently stable spark
• Iridium alloy center electrode: its density is about six times that of platinum, and its very high melting point suits modern high-efficiency engines
• Tapered cut ground electrode: a reduced-quenching design that improves ignitability, starting, idling, acceleration and throttle response
• Solid copper core: 98 percent pure copper for superior heat dissipation, conductivity and a wide heat range
• Trivalent metal plating: resists corrosion and seizing, so installation and removal are easier
• Ceramic insulator: alumina silicate ceramic for strength and heat transfer, with triple seals to prevent leakage
• Resistor type: reduces radio frequency interference
