Is there any difference (performance wise) between the stock coil pack and this one http://modernperformance.com/dcx/msd_coil.shtml ???

 

Yes there is...The msd coil puts out a little more than the stock one.I heard the "screamin demon" coil pack is exactly same as stock though.This is from reading thru many forums over the years..I could be wrong...but I dont think I am..:P

 

MSD is the way to go. It'll put out more power, used in conjunction with iridium plugs you'll have much better throttle response.
