I used Delphi coils, GN10328 and NGK plugs, 97506 purchased from RockAuto.com for $24.89 and $14.12 respectively. If you look on realoem.com and see how many various models of cars the Bosch coil is specified for, it doesn't seem there's anything special about it. Sure, we have a high HP twin turbo, but it seems the coil doesn't care.
The NGK is the plug specified for the stock 4.4 s63tu motor by NGK. I have read opinions of others on this forum that it is a colder plug than the stock Bosch plug. I haven't been able to confirm that, so I took NGK's word for it and used theirs. Both the coils and plugs seem to work just fine.
