hey, "I KNOW" MACH is a smart guy, I've been at this mustang game only 2 years now, so I know I don't know everything..
but when you can't believe a MAG article, what can you believe??

(at least the pictures are nice to look at..)
and as for plugs, I only run conventional plugs as well, they're cheaper, and do me good...
and lethal5oh, here's what I'd do if I were you (AND you plan on souping your car upto the 300 hp levels, otherwise stock ignition is good enough) ... get their distributor module only if you've got high miles on your car, get normal motorcraft plugs, gap at .049 (32ASF's), get the wires and coil, and you should be good to go..
