The power arc replaces the coils? Are you sure he did not just put different coils under the tank?
I am not ruling it out but I have never seen an ignition system where you remove the coils.
Anyways, partsnmore.com has new coils very similar to the ones that came stock.
Unless it is a money issue, I would do this instead of throwing on old coils with possibly cracked insulation and bad wires.
The ride IS the adventure. The destination is just to get gas!
