Plenty have tried the Accel coil, and on the positive side nobody has yet been able to show any objective benefit
I have one and I noticed a considerable ammt of increased fuel efficiency, Let me clarify, I lost some fuel efficiency w/ a rising rate FPR, I gaind it back w/ the accel over the stock coil pack.
and on the negative side many have experienced failures and had to replace it.
I am on my second coil pack, and I can undoubtedly say, the reason for the coils failure was the crappy magnacore wires I had on it. Those wires have very poorly made connectors where they plug into the coil pack(mine would barely stay on the coil pack) and they let in all sorts of debris and miosture which led to the corrosion of the coil terminals and ultimately the failure of the Coil itself.
