This is a most performance spark plugs on market. Great performance and superb acceleration. This is a great low cost mod for any bike.
Excellent performance and great quality. Bike runs well with the new spark's.

Complete junk!! The threads broke off the plug hand tight.
These are junk!! It broke off in my motor and had to be professionally removed. A simple 2 second job was turned into a whole weekend of no riding and a repair bill.
