Spark plugs are not all alike. With the world-famous DENSO U-Groove spark plug it's easy to see, thanks to its patented U-shaped ground electrode. The U-Groove forms a channel for the spark nucleus to form at the instant of ignition, limiting quenching to generate a more potent spark. The premium features don't stop there: DENSO's distinctive five-rib insulator in purified alumina prevents leakage and flashover, while dual internal copper-glass seals and a copper-core center electrode with nickel-alloy tip assure reliable spark delivery. To keep your engine running smoothly, its spark plugs must fire 25 times a second or more. If just one spark plug skips a beat you'll know it instantly, with rough running, poor acceleration, and reduced fuel economy. DENSO U-groove spark plugs combine dependable performance and superior value.
Important information: Single spark models (F Series) need one plug per cylinder. Twin spark models require one main and one auxiliary plug per cylinder. The main and the auxiliary are the same plug, so you would need two per cylinder or four per bike. The following bikes are twin spark models:
R1200 R up to 2010
R1200 GS (2005-2009)
R1200 GS Adv (2005-2009)
R1200 RT (2005-2009)
