• Sold individually - order the correct quantity for your engine's cylinder count

Features

• Tapered-cut iridium center electrode reduces the voltage required for spark, delivering a brighter, stronger spark from the existing ignition system
• Iridium's density (6x that of platinum) and high melting point suit modern high-efficiency engines
• Platinum-tipped ground electrode contributes to extreme longevity
• 98% pure copper core offers strong heat dissipation, conductivity, and a wide usable heat range
• Trivalent metal plating provides strong anti-corrosion and anti-seizing properties for easier installation and removal
• Smallest available tip diameter minimizes wear for extended service life

Product Description

The NGK 6481 (ILFR6B) is a Laser Iridium spark plug shared across a notably wide range of platforms - Subaru's EJ-series boxer engines (Impreza, Forester, Outback, Baja, B9 Tribeca), the related Saab 9-2X (a rebadged Impreza WRX), Hyundai's Genesis Coupe 2.0T, Land Rover's LR2 3.2L, and select Volvo applications. Its tapered-cut iridium center electrode is engineered to lower the voltage needed to fire a spark, producing a brighter, stronger spark from the vehicle's existing ignition system without any other modifications.

A platinum-tipped ground electrode pairs with the iridium center electrode for extreme longevity, while the smallest available tip diameter helps minimize wear over the plug's service life. The 98% pure copper core supports strong heat dissipation and conductivity across a wide operating range, and trivalent metal plating protects against corrosion and seizing in the cylinder head over time.

This is a strong OE-quality replacement across the covered Subaru, Hyundai, Land Rover, and Saab models, and it's manufactured as the top-choice OEM iridium plug used across several of these platforms directly from the factory. Given the breadth of vehicles this plug covers, cross-referencing your engine's OE spark plug part number is a good practice to confirm fitment for your specific model and trim, especially for the Volvo and B9 Tribeca applications where exact years weren't independently confirmed.
