Well what does it excatly do? loss of power? Misfire? Surge?
All R32 have problems with the standard coils at this age.
My car and my best mates had the same problem and all the things you can do to stop it only give you a little more time until you buy splitfire coilpacks around $600 now i think.
Things you can do:
Make sure the boost isnt wound up too high
Reduce the spark plug gap to no smaller than 0.7mm
Check condition of Air Flow Meter, i had dramas till i found a great guide on these fourms to fix AFM's
Clean coil packs and rubbers externaly
