Bosch Super and Super Plus spark plugs offer outstanding value for a huge variety of vehicles. Comprehensive testing by Bosch has proven that Super plugs deliver reliability and durability in all conditions.
Super Plus plugs offer even higher performance. The yttrium-enhanced electrode increases service life by up to 50% compared to standard copper core plugs.
The Super advantages at a glance:
Copper core dissipates heat, guarding against thermal overload
Nickel-chromium alloy of the centre electrode provides corrosion protection for the copper core and ensures a high level of resistance to spark erosion
Maximum interference suppression
The Super Plus advantages at a glance
Yttrium enhanced electrode for longer life compared to standard copper core plugs
Tapered v-profile nickel chromium centre electrode for increased fuel ignitability
Angular, five-ribbed insulator design to prevent misfiring caused by current leakage
