NGK Iridium

Spark plugs from NGK guarantee top quality! Over 90% of all Japanese motorcycles are originally equipped with NGK products!

As inconspicuous as a spark plug may be, its effect on fuel consumption, starting willingness, and engine performance is substantial. Vehicle manufacturers have determined the optimal spark plug for a bike through extensive testing – therefore, always adhere to the manufacturer's specifications!

All spark plugs marked with an R have an integrated 5 kOhm suppression resistor, which is only necessary if 5 kOhm suppressor caps are not already being used. In total, 5 kOhm suppression per cylinder is sufficient; more than 10 kOhm can reduce the ignition energy of the spark.

IMPORTANT NOTICE:
Before (!) purchasing and before (!) installing spark plugs, you must always ensure that the selected spark plugs precisely match the specifications and approvals from the manufacturer’s operating manual! If your operating manual is not readily available, please contact us! Use exclusively products and specifications that are approved for your vehicle! Failure to comply may result in severe damage to your vehicle for which we deny any liability and warranty in advance!
