I think you need to have a hotter-than-stock ignition coil on the motor for this mod to work well, no? Or will a stock coil still do the job okay if using the stock gap on the cutbacks?

Though I've always upgraded the coil and wires along with the mod, the references only mention 8-10hp gain from the cut-back mod.
So, I think it would work with stock gap; the unshrouding principle is the same.

Re: cut spark plug tips? (guywade)
in the uk you can buy a plug with 3 bars bent over the electrode and the spark shoots out 3 ways very good , you can use them with standard systems or you can the f1 type plugs with no bar just electrode downside with these is cost, upgrade in system and tends to run hot, if i can find some i will post pics. :cheers: :cool:

Re: cut spark plug tips? (Mad AUSSIE)
Has anyone ever tried those copper Bosch 3 tip plugs in a vette? I think that is what Mad Aussie is talking about. I didn't know they even existed, but my brother got a set for his 944 turbo (you shouldn't put platnums in a turbo). Supposedly, this would eliminate the need to index or cut back the electrodes. Even if they cost a little more, cutting back the electrodes takes up time (of which I have little). Also, they are much beefier than the +4s.
I just bought a new set of NGK's, but I'm going see if they sell these Bosch plugs in our size/heat range.
