Just installed a set of these in my Kaw Drifter (motorcycle)at 8000 miles. Expected slight gain in throttle responce. They definately improved the responce throughout the entire powerband but was extremely happy to learn that a vibration that it has had since I bought it new .....is now completely GONE !!! (the standard NGKs that I pulled out were fine) And I'll swear that it is quieter when comming off of the throttle. Used to pop and snort when I let off of her and now.....quiet as a church mouse. I would imajine that not as much raw fuel is making its way to the pipes. Let's add this up.....snappier throttle, less vibrations and quieter. These plugs are friggin AMAZING . Puts a smile on my face every time I ride her.
