FAQs

1. What's the difference between RLH00100/B and RLH00100/C?
RLH00100/B has been replaced by RLH00100/C as Royal Enfield's latest part number for the same Bosch YR7MES spark plug, across J-Series bikes.

2. Will this spark plug fit my Classic Reborn or Meteor 350?
Yes—these J‑Platform models use the RLH00100/C spark plug. It’s factory-spec for these bikes.

3. Can I use this in older UCE models or 650 Twins?
No. Those models typically use a different spark plug type/design. Use OEM-specified plug for your model in such cases.

4. How often should I replace the spark plug?
Replace every 10,000–15,000 km or when you notice hard starts, misfires, or reduced performance. Always use a genuine RE plug.

5. OEM vs aftermarket—why choose this?
Only the Bosch YR7MES (RLH00100/C) meets Royal Enfield’s thermal and gap specifications. Generic plugs may not perform reliably under Indian conditions.
