The symptoms that led me to change them was occasional hesitation under load, stuttering in the lower RPMs at full throttle, and a subtle roughness in idle. A weird byproduct of changing coils is it is also a bit quieter (less drone) on the highway now (remus race exhaust, test pipes), which I can only attribute to better combustion.
Seems to be a few people in uk having problems with coilpacks lately, at least you know they are done now though, I have done 46000 miles at moment on a 58 plate and am having spark plugs replaced soon so may just get these while my mechanic has everything open, as I plan on doing 6/7 track days in 2016
