Denso U16FSR-UB Spark Plug
One of the most important characteristics of most of the candles Denso is given by the electrode mass, with groove U. The candles DENSO, with the U-groove patented, allow complete combustion by allowing the spark to fill the space created by the shape ' U '. The ball of fire created in the U-groove develops a flame front more extended and hot, that virtually eliminates excessive contamination and starts defective due to poor fuel mixtures. The U-shaped groove is positioned on the electrode grounding, because this location is the least affected to wear. With this guarantee that the advantages of the U-groove will persist for the duration of the spark plug. CAUTION: To check compatibility with your bike or scooter consult the catalog Denso
