NGage BN8RTIIA-9 Double Iridium Spark Plug – Royal Enfield Himalayan 450, Guerrilla 450 & Hero Xpulse 200 4V / Pro

NGage BN8RTIIA-9 Double Iridium Spark Plug – Made in Japan

NGage BN8RTIIA-9 is a Double Iridium motorcycle spark plug specifically listed by NGage for the Royal Enfield Himalayan 450, Royal Enfield Guerrilla 450, Hero Xpulse 200 4V and Hero Xpulse 200 4V Pro.

This is the exact BN8RTIIA-9 application published in NGage Master Catalogue V4.9. It should not be substituted with another NGage Double Iridium plug simply because the motorcycle has a similar engine capacity or because another plug looks physically similar.

Confirmed BN8RTIIA-9 Compatibility

Double Iridium Electrode Design

NGage describes its Double Iridium spark-plug range as using an Iridium firing pin and Iridium electrode pin. The manufacturer specifies a 0.6 mm Iridium tip and promotes the design for improved ignitability and durability.

NGage also describes a 360-degree laser-welding process for the Double Iridium tip. The manufacturer positions this design around a more stable ignition event and improved combustion compared with its single-tip comparison.

98% Pure Copper Core

NGage states that its Double Iridium design uses a 98% pure copper core. According to the manufacturer, the copper core improves heat dissipation, supports reliable starting and helps prevent spark-plug overheating.

High-Grade Alumina Silicate Ceramic

NGage specifies a high-grade alumina silicate ceramic insulator, intended to provide robust electrical insulation and reduce the risk of dielectric punch-through through the ceramic body.

Manufacturer-Published Performance Claims

NGage markets the Double Iridium series around the following potential benefits:

• Better combustion
• Reduction of misfires
• Improved acceleration
• Easier starting in cold / wet weather
• Improved fuel-efficiency potential
• More stable idle
• Long service-life potential

These are manufacturer performance claims, not guaranteed gains. Actual starting, acceleration, fuel economy and idle quality depend on the complete engine and ignition system, including coil condition, fuelling, compression, sensors, injector condition, wiring, maintenance and correct installation.

Himalayan 450 Fitment

NGage Master Catalogue V4.9 specifically assigns BN8RTIIA-9 to the Royal Enfield Himalayan 450.

Do not confuse this with the older Himalayan 411 application. NGage lists the older Himalayan 411 under a different Double Iridium part number, B8RII-8.

Guerrilla 450 Fitment

The Royal Enfield Guerrilla 450 is also explicitly listed by NGage for BN8RTIIA-9.

Even though other Royal Enfield motorcycles may use NGage Double Iridium plugs with similar-looking part numbers, only use the exact plug specified for the motorcycle.

Hero Xpulse 200 4V / 4V Pro Fitment

NGage lists:

• Hero Xpulse 200 4V – BN8RTIIA-9
• Hero Xpulse 200 4V Pro – BN8RTIIA-9

Important Xpulse distinction: NGage lists the older Xpulse 200 2V / Xpulse 200T under a different Double Iridium application, B8RII-8. Do not assume the 2V and 4V engines use the same NGage plug.

Important NGage Spark Plug Cross-Reference

BS4 / BS6 Note

NGage labels its Double Iridium spark-plug range as compatible with both BS4 and BS6 vehicle applications. This does not make BN8RTIIA-9 a universal BS4/BS6 spark plug. The vehicle must still appear in the correct application chart or otherwise have verified specification compatibility.

How Many Spark Plugs Will I Receive?

This listing supplies 1 × NGage BN8RTIIA-9 Double Iridium Spark Plug.

If a motorcycle requires more than one plug, order the required quantity only after confirming the engine specification. Do not assume quantity from another model.

Fitment / Return-Prevention Note

Spark plugs are specification-sensitive ignition components. Before ordering, confirm:

• Exact part number: BN8RTIIA-9
• Exact motorcycle model
• Engine / model generation
• Required quantity
• Existing plug specification if the motorcycle has been modified or the engine is non-standard

Do not install B8RII-8, DH7RTII-8, VH8RTII-9 or another NGage plug in place of BN8RTIIA-9 unless that alternate specification is independently confirmed for the exact motorcycle.

Installation Note

Professional installation is recommended if you are unsure of spark-plug servicing.

• Work only on a cool engine.
• Confirm the part number before removing the existing spark plug.
• Clean around the spark-plug area before removal so debris cannot fall into the engine.
• Start the new plug by hand to reduce the risk of cross-threading.
• Use the motorcycle manufacturer's specified spark-plug tightening torque.
• Do not over-tighten.
• Inspect the ignition cap / coil connection during installation.
• Do not alter the electrode gap unless specifically required by the motorcycle or spark-plug manufacturer.
