NGK LMAR8A-9 Spark Plug – 4313

The NGK LMAR8A-9 (4313) is the exact OEM-specification replacement spark plug trusted by major motorcycle manufacturers right from the factory line. Designed to deliver consistent, reliable ignition performance, this standard plug is the exact factory fitment for incredibly popular middleweight platforms like the Yamaha Ténéré 700 and MT-07. Built with a durable nickel alloy electrode and a deep-seated copper core, it ensures optimal heat dissipation to prevent pre-ignition, maintaining a smooth idle and reliable power delivery mile after mile.

Features

• True OEM Reliability: This is the exact factory-specified replacement plug for your engine, ensuring your bike runs exactly as the manufacturer intended without any guesswork.

• Copper Core Technology: Features a highly conductive, deeply inserted copper core that rapidly transfers heat away from the firing tip, keeping the plug operating within its optimal thermal window.

• Trivalent Metal Plating: The threaded body utilizes NGK's proprietary silver-toned plating, which provides superior anti-corrosion properties and prevents the threads from seizing in the cylinder head.

• Corrugated Ribs: Specially designed ribs on the ceramic insulator prevent voltage "flashover" that can cause engine misfires in damp or high-humidity riding conditions.

• Pure Alumina Silicate: The advanced ceramic insulator provides exceptional dielectric strength and physical durability to withstand the intense vibrations of off-road and street riding.
