BOSCH and NGK spark plugs are among the best your machine can get. We offer them in standard and iridium versions:
– BOSCH iridium, with an extremely thin positive electrode made of a special metal alloy, with a replacement interval of up to 100k km.
– standard NGK, with one electrode, with a standard replacement interval of 20k km
– Iridium NGK, with extremely thin positive electrode made of special metal alloy, with replacement interval up to 100k km
Iridium spark plugs have the advantage of being able to ignite a richer mixture than standard spark plugs, in addition to several times longer life. According to the manufacturer, they contribute to increased performance, but according to our measurements on the brake the difference was not noticeable. The truth is that we do use them on race machines (Yamaha YZF-R6 and BMW S1000RR), but for durability and reliability reasons rather than for the power increase.
