What makes DENSO spark plugs different? Find out here.
Unique U-Groove Ground Electrode
The patented U-Groove spark plug enables complete combustion by allowing the spark to fill the gap created by the U shape creates a larger and hotter flash front that eliminates excessive fouling and erratic starts caused by poor fuel mixtures.
The U-Groove plug employs a unique, channeled ground electrode which generate a larger spark nucleus at the point of ignition. This means improved flame travel and producing more complete, consistent, and efficient combustion.
Better Fuel Efficiency and Improved Throttle Response
The U-Groove ground electrode provides superior stimulation and inhanced combustion, resulting in better fuel efficiency and improved throttle response.
Lasts twice as long as conventional plugs
