Denso W22FS-U 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;. 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.
