Spark Plugs from Bosch

More than a century ago, in combination with a high-voltage magneto, Bosch presented the first spark plug.

Bosch was awarded the patent for this ground-breaking system on 7 January, 1902. Manufactured using world-class Bosch technology, Bosch Ltd. Spark Plugs meets world-class standards of reliability and performance. A testimony to this is the fact that Bosch Ltd. is the preferred OE supplier for companies like Bajaj Auto, Hero Honda, Yamaha, T.V.S., Kinetic, Maruti, Hindustan Motors, PAL and M&M, to name a few.


  • Highly effective anti-tracking barriers Prevents arcing which would otherwise result in misfiring
  • Suppression resistor Reliable functioning of all electronic systems and interference-free radio reception
  • Ground electrode The number of electrodes, their configuration and their geometry have a decisive effect on ignition-spark techniques and service life
  • Nickel-plated spark-plug shell and screw-in thread Guards against corrosion and prevents seizure in the aluminum cylinder heads
  • Heat-shrink assembly Guarantees 100% gas tightness and precise heat rating
  • Compound centre electrode The copper core with high thermal-conductivity characteristics inside a non-wearing, chrome-nickel sheath ensures that the operating temperature is reached quickly. Protects against thermal overloading, conventional corrosion and spark erosion
  • Range

    BOSCH Super 4

    • The technology combination which is unique throughout the world inted, silver-plated centre electrodes
  • Optimum engine performance throughout the plug’s operating time, even under extreme operating conditions

BOSCH Super: pointed ground electrode for 2 / 3 wheelers

The ground electrode has a structured profile and is less vulnerable to wear than centre electrode. As a result, the advantages of this structured profile can be utilised throughout the entire service life of the spark plug.

  • Higher ignition reliability due to faster flash-over of the spark and ignition of the mixture
  • Additional cold-start reliability even when battery voltage is low
  • Improved combustion protects the engine
  • Since misfiring is avoided, fuel consumption drops even more

BOSCH Super: twin electrode for 2 wheelers

  • Increased ignition reliability throughout the spark plug’s entire service life
  • Improved cold-start characteristics
  • Low ignition-voltage requirement
  • Self-cleaning effects in case of sooting
  • Two ground electrodes increase the plug’s service life
