2 main benefits of the R8 coil packs:
1) they're red so they will make your car go faster (engine bling)
2) they have a stronger coil than the stock coil packs. Stock coils are prone to failure with tuned cars. Coil pack failure can be quite inconvenient as it can (worst case) cause the ECU to shut down a cylinder = limp mode, total loss of power, car runs really rough. If you're out of town or more than 500m from a dealer this is a total pain.
Certainly cheap insurance and at worst case something nice to look at under the hood (once you remove the engine cover).
