• Spark plugs from NGK are a guarantee of premium quality! More than 90% of all Japanese motorcycles are factory-fitted with NGK products! A spark plug may seem a rather humble component, but its effect on consumption, startability and engine performance is huge. Vehicle manufacturers conduct exhaustive tests to find the optimal spark plug for a particular bike, so be sure to adhere to the factory specification! Only very rarely is a different heat range advisable: in town riding or during the running-in phase, spark plugs sometimes do not burn themselves clean, and they then develop a black to greyish-white deposit (fouling), which results in the bike being difficult to start. If the carburettor is adjusted correctly, then a lower heat range may improve this situation. IMPORTANT: A plug with too low a heat range can lead to engine damage! You should therefore always check first with your authorised repair shop. All spark plugs marked "R" have an integrated 5 kOhm interference-suppression resistor, which is only necessary if 5 kOhm suppressor caps are not already used. In general, 5 kOhm suppression per cylinder is sufficient; more than 10 kOhm can reduce spark ignition energy. If you are having trouble finding the right spark plug for your vehicle, please use our product listing under "My Bike" (top navigation bar).

• IMPORTANT NOTE: Before (!) you purchase and before (!) you install spark plugs, you must always ensure that the spark plugs you have chosen exactly meet all the requirements and criteria in the manufacturer's manual! If you cannot find your owner's manual, contact your local motorcycle workshop or the motorcycle manufacturer! Only use products and specifications approved for your vehicle! Failure to do so can cause serious damage to your vehicle, for which we reject all responsibility and liability in advance!
