Denso's patented U-Groove spark plug enables complete 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 flash front that virtually eliminates excessive fouling and erratic starts caused by poor fuel mixtures.

Comments about Denso Hot U Resistor Spark Plug:
I have had this plug in my 2001 cr125r for about 3 weeks now and still running strong. I ride at least once a day and I also ride with my little girl on with me so the plug can with stand slow and fast riding conditions. My bike does have lots of aftermarket parts so that might make a diffence but I like them.
Service and delivery comments:
great schematics to look up parts that are needed. some prices are a little high but worth it.
Bottom Line Yes, I would recommend this to a friend
