BMW motorbike spark plug

As inconspicuous as a spark plug may be, its effect on the engine's fuel consumption, willingness to start and enjoyment of performance is enormous. The ignition voltage generated by the ignition coil is transmitted to the spark plugs via the spark plug cables. There, the ignition spark generated by the ignition voltage jumps over between a ceramic-insulated centre electrode and a ground electrode fixed to the fastening thread, thus starting the combustion process.

ImPORTANT NOTE:
Before purchasing as well as installing spark plugs, you must always make sure that the selected spark plugs correspond exactly to the specifications and approvals from the manufacturer's operating manual! If your operator's manual is not to hand, contact your specialist workshop! Only use products and specifications that have been approved for your vehicle! Failure to do so may result in serious damage to your vehicle, for which we disclaim all liability and warranty in advance!
