If your Royal Enfield starts feeling rough, hesitates on throttle, misfires, or takes longer to start—your spark plug is one of the first service items to check. Royal Enfield 574158/A (SPARK PLUG-M10) is the genuine OEM spark plug used on the 411 Himalayan and multiple 650 platform motorcycles, manufactured to the OE specification (commonly listed as Bosch R6 UR5CC). 

Unlike generic aftermarket plugs that may “fit” the threads but vary in reach, heat range, or resistor spec, this plug is designed to deliver consistent ignition, stable idle, clean combustion, and reliable fuel efficiency for the exact engines listed below. 

Important: This part number is for Himalayan 411 / Scram 411 and the 650 family. It is not the correct spark plug for Meteor 350 / Hunter 350 / Classic 350 (J-Series) or Himalayan 450 / Guerrilla 450—those use different OE plug codes.

Key Features 

  • Genuine Royal Enfield OEM spark plug (part no. 574158/A) 

  • OE spec widely referenced as Bosch R6 UR5CC 

  • Correct M10 plug type for the verified models listed below 

  • Helps restore smooth idle, clean pickup, and easier starting (common spark plug symptom fix)

  • Reliable daily riding + touring performance

  • Prevents misfire-related stress on ignition components when replaced on time

  • Ideal for routine service / preventive maintenance

  • Lower return risk because fitment is model-verified (not “universal”)

FAQs 

1) Is 574158/A genuine Royal Enfield OEM?

2) Will this fit Meteor 350 / Hunter 350 / Classic 350 Reborn?

Himalayan/Scram (single-cylinder) typically use 1. 650 Twins (twin-cylinder) typically use 2.
