Bavarian Autosport High-Performance Ignition Coils

is there a big difference with the high prefomance coil and the stock coils
for a 1994 325i do you get a boost or it feels the same, i`m thinking of getting
irridium spark plugs prefomance ignition coil and a bavarian prfomance chip or tunermotosport chip which ever is better is this wise or a waste of money
anybody got feed back thanks
