I went with a set from RM Stator out of CA. The coils are made in CN. I bought 5, 4 to install and 1 as a spare. I'm riding the bike from Cincinnati to Seattle via Joshua Tree this Sunday. One of the coils arrived damaged (connector to coil seam was split), but RM Stator sent an RMA label as soon as I reported the problem.
They should be issuing a refund as soon as they receive the part.
I also ordered a Fenda Extenda. Hopefully it arrives by Sat.
The throttle response is much better with the new coils.
I'll install Iridium plugs next.
