Has anyone used these spark plugs on a SD and if so was there any noticable effects?

We've used them with great success in LC4 engines. With amazing results. Better starting & idling, smoother, more torque en top-en power. But the LC4 is not the LC8. The LC8 uses a special type of plug to start with.
BUT... Brisk plugs are also known to cause engine failures by electrodes and ceramic material breaking off. Not nice. I'm not brave enough to put them in my SD...
