NGAGE Double Iridium Spark Plug VH8RTII-9

The NGAGE VH8RTII-9 Double Iridium Spark Plug is a performance-focused motorcycle ignition component designed for a range of verified KTM, Bajaj and Triumph applications. Riders Junction confirms the VH8RTII-9 part number for motorcycles including the KTM Duke 390, Duke 200, RC 200, RC 390, Adventure 250 and Adventure 390. The same part number is also listed for selected Bajaj Pulsar triple-spark models and Triumph Speed 400, Speed T4 and Scrambler 400 X. The plug uses 360-degree laser-welded double-iridium tips with 0.6 mm firing and electrode pins, providing a precise spark designed to support efficient combustion and durable ignition performance. A high-grade alumina-silicate ceramic insulator helps reduce spark leakage, while a 98-percent pure copper core improves heat dissipation. A malleable copper gasket supports a secure seal during installation. The design is intended to improve starting reliability, acceleration, combustion efficiency and idle stability while reducing misfires. Because spark-plug fitment is engine-specific, the VH8RTII-9 part number should always be matched against the exact motorcycle application before installation.
