Description

The NGage VH8RTII-9 Double Iridium Spark Plug is a motorcycle ignition component developed for select modern, fuel-injected motorcycles, including the Hero Xpulse 210 4V. Manufactured in Japan, this spark plug is part of NGage’s Double Iridium series and is specified for use in both BS4 and BS6 compliant motorcycles, as stated by the manufacturer.

This listing focuses exclusively on its application for the Hero Xpulse 210 4V, where the VH8RTII-9 spark plug specification is listed by NGage in its official compatibility chart. It is intended as a direct replacement spark plug for this motorcycle, without modification.

Designed for Hero Xpulse 210 4V

The Hero Xpulse 210 4V represents a new-generation, liquid-cooled, fuel-injected single-cylinder platform with updated combustion and ignition system requirements. NGage specifies the VH8RTII-9 spark plug for this motorcycle, indicating alignment with the engine’s ignition design and operating parameters.

For the Hero Xpulse 210 4V, the VH8RTII-9 is intended to function as a like-for-like replacement for the factory-specified spark plug type. It is not positioned as a tuning component or a modification-driven upgrade, but as a specification-correct ignition part for routine service or replacement.

Double Iridium Spark Plug Construction

NGage classifies the VH8RTII-9 as a Double Iridium spark plug, meaning iridium material is used on both the center electrode and the ground electrode.

Iridium is used in modern spark plug construction due to its high melting point and resistance to electrode erosion during repeated ignition cycles. This construction approach is commonly applied in motorcycles with high-energy ignition systems and tightly controlled combustion environments.

The double-iridium configuration is intended to maintain consistent electrode geometry over extended operating periods under normal riding conditions. NGage does not publish electrode dimensions, spark-gap values, heat-range explanations, or service-interval figures for this model.

BS4 and BS6 Compatibility

NGage specifies that the VH8RTII-9 spark plug is compatible with both BS4 and BS6 vehicles. This makes it suitable for use across production years that fall before and after the BS6 emission-standard transition, provided the motorcycle is included in the compatibility list.

For the Hero Xpulse 210 4V, this ensures suitability across emission-compliant variants without requiring a change in spark plug specification.

No emission-reduction, fuel-efficiency, or tuning claims are made for this product.

Manufacturing Origin

The VH8RTII-9 spark plug is manufactured in Japan, as stated on NGage’s product packaging.

NGage does not publish further information regarding production processes, certifications, or testing standards for this model. The country of manufacture is provided here as factual product information only.

Intended Use

The NGage VH8RTII-9 is intended for routine replacement during scheduled maintenance or spark-plug service intervals recommended by the motorcycle manufacturer. It is suitable for everyday road and light off-road use on the Hero Xpulse 210 4V within standard operating conditions.

This spark plug is not positioned by NGage as a racing-only, track-specific, or specialized tuning component.

Fitment Accuracy

Correct spark plug selection is critical for engine operation and long-term reliability.

The VH8RTII-9 should be installed only on motorcycles listed in the compatibility section below. Use on non-listed motorcycles is not recommended.

For the Hero Xpulse 210 4V, this spark plug is specified by NGage as the correct application for this engine platform.
