[s-cars] 034efi AAN coil upgrade kit

[auctionpics at cox.net]

Can someone answer for me if the $330 coil deal from 034 is the same as
the DIY coil idea?

also is the cost much difference with the 034 vs DIY?

if you use the 034 setup and a coil goes bad what do you do? is it just
a case of buy a coil,plug it in and go?

and with the 034 setup you just remove the old setup with the cover and
plug and go with the new setup with no cover,no extra work?

thanks dave
