Style chooser

hi,

my mechanic suggested to me to 'double coiled' my spark plugs. he said it would increase the spark - better combustion and reduce fuel consumption. I've seen the installation, is not that tricky except that you would need to modify the distributor (for proton), where he put a spark plug into it (I didn't see inside the distributor) and connect it to another coil. the idea is to have 2 coils connected to the distributor.

any comments? it would cost me RM200 to install, but I need some...
