I know one thing! for me, i find such a config (2 plugs per hole A engine) very interesting, indeed! clean set up... dual coils, 12-v (I assume) and 'clean as a whistle!' install/engineering. never seen one before.
There are some changes that could be made that would surely add to performance, output and 'throttle response!'. I am wondering if there is any dyno info out there, ie... stocker and a dual plug set up such as this as to potential or actual gains achieved!
surely, it has an awesome throttle response. noticeably, sounded sweet to me pulling into the garage!....
