NGAGE Iridium Spark Plug B8RII-8

The NGage B8RII-8 spark plug is manufactured in Japan, as stated on the product packaging. NGage does not publish further details regarding production processes, quality certifications, or testing standards for this model. The country of manufacture is provided as factual information only.

The NGage B8RII-8 Double Iridium Spark Plug is a premium motorcycle spark plug developed for select Royal Enfield motorcycles, including the Himalayan and the full 650 platform range listed below. Manufactured in Japan, this spark plug is part of NGage’s iridium series designed for modern motorcycle ignition systems used in both BS4 and BS6 applications.

NGage specifies the B8RII-8 as a Double Iridium spark plug, indicating the use of iridium material on both the center electrode and the ground electrode. Iridium is chosen in spark plug manufacturing for its ability to withstand high combustion temperatures while maintaining electrode stability over time. This construction approach is commonly used in modern motorcycles that operate under tighter emission and combustion control requirements.

Application for Royal Enfield Motorcycles

The B8RII-8 spark plug is listed by NGage for use in multiple Royal Enfield motorcycles across two distinct engine platforms:

• The Royal Enfield Himalayan 411 & 450

• The Royal Enfield 650 series, including Interceptor 650, Continental GT 650, Bear 650, Super Meteor 650, Shotgun 650, and Classic 650

These motorcycles share ignition system requirements that align with the B8RII-8 specification as published by NGage. This spark plug is intended as a direct replacement within these applications, without modification.

The Royal Enfield 650 platform spans multiple body styles and riding formats, but ignition requirements remain consistent across these models. Listing each model explicitly ensures clarity for riders searching by motorcycle name rather than engine family or platform grouping.

Compatibility with BS4 and BS6 Vehicles

NGage specifies that the B8RII-8 spark plug is compatible with both BS4 and BS6 vehicles. This makes it suitable for Royal Enfield motorcycles produced before and after the transition to BS6 emission standards, provided the motorcycle is included in the compatibility list.

No additional emission-related claims, tuning effects, or regulatory certifications are stated by NGage for this product, and none are implied here.
