A key feature of DENSO spark plugs is the patented U-groove ground electrode. This enables complete fuel combustion by allowing the spark to fill the gap created by the 'U' shape. The ball of fire created in the U-groove develops a larger and hotter flame front that virtually eliminates excessive fouling and erratic starts caused by poor fuel mixtures. The complete combustion from DENSOs U-groove design leads to greater fuel efficiency.
