Description
The NGK LKR7BIX Iridium Spark Plug is a precision-engineered ignition component designed for modern single-cylinder motorcycle engines that use the LKR7BIX spark plug specification. Built with NGK’s fine-wire iridium centre electrode, this spark plug is intended to provide consistent ignition performance across everyday riding conditions.
Iridium is used for its high melting point and durability, allowing the electrode tip to remain stable over extended service intervals. This helps maintain reliable spark quality and reduces the likelihood of carbon fouling during normal operation. As a result, the spark plug supports smooth engine behaviour and dependable starts over long-term use.
The LKR7BIX features NGK’s proven ceramic insulator and plated metal shell, designed to handle regular thermal cycles without compromising insulation integrity. These construction elements contribute to ignition consistency and long service life when installed in engines designed for this specific spark plug specification.
For Royal Enfield motorcycles built on the J-series 350 platform, the NGK LKR7BIX serves as a compatible replacement where the OEM spark plug specification matches LKR7BIX / LKR7BIX-P. Its design aligns with the ignition requirements of these engines, making it suitable for daily commuting, touring, and mixed riding conditions when correctly applied.
This spark plug does not alter engine tuning, compression, or engine characteristics. It functions as a high-quality ignition component intended to maintain stable combustion and dependable operation over time.
