Spark Plugs

Has anybody used the ”Brisk” performance spark plugs? Doing my valve adjustment and since the plugs are readlily excessable now, (all the plastics and heat shields are out of the way), I was thinking that it might not be a bad idea to change the plugs if these Brisk performance plugs are as good as advertized.
1. Higher HP and torque by up to 3 %
2. Increased economy by up to 5%
3. 360° Firing Technology
4. Improved acceleration by up to 15 %
5. 25,000 miles – 40,000 km duration
