Iridium Spark Plug

Choose Iridium spark plugs from NGK in guaranteed top quality. Because as inconspicuous as a spark plug may be, its effect on fuel consumption, willingness to start and the engine's enjoyment of performance is huge. Iridium IX spark plugs from NGK go one better by ensuring optimum ignition and smooth engine running. Misfiring and misfires are prevented. These spark plugs offer excellent starting behaviour, better acceleration through more spontaneous throttle response, they reduce fuel consumption, counteract sooting in stop-and-go traffic. In addition, the service life of NGK Iridium IX spark plugs is at least twice as long as that of standard spark plugs.

• excellent starting behaviour
• better acceleration due to more spontaneous throttle response
• reduce fuel consumption
• counteract fouling in stop-and-go traffic
• considerably longer service life compared to standard spark plugs

If you cannot find the right spark plug for your vehicle at first go to "My Bike" or have a look at the "Cross Reference List", which can be found under documents.

IMPORTANT NOTICE:
Before (!) buying and before (!) fitting spark plugs, you must always make sure that the spark plugs you have chosen correspond exactly to the specifications and approvals in the manufacturer's owner's manual for your vehicle. If your owner's manual is not available, contact your workshop or the motorbike manufacturer. 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.

Good to know:

• all spark plugs marked with an "R" have an integrated 5 kOhm suppression resistor, which is only necessary if 5 kOhm suppression plugs are not already used. A total of 5 kOhm interference suppression per cylinder is sufficient, more than 10 kOhm can reduce the ignition energy of the spark.
• For almost every NGK standard spark plug there are corresponding NGK Iridium IX spark plugs, which technically bring the advantages mentioned above. However, in practice it can occasionally happen that the desired improvements do not occur in operation. Therefore, the corresponding references are to be seen as an option, a suggestion. In case of doubt, it is always advisable to ask the vehicle manufacturer whether the replacement is worthwhile and does not lead to any technical problems.
