I bought 3 coils from Advance, to get 1 good one. I had a new OEM module, and took it with me, hooked up my Caspers tester, and showed the clerk what was going on. Did this til I got a good coil pak.
Without testing, it's a crap shoot.
All the ap stores are going to sell you the same stuff. Take your choice. Most have "lifetime" warrantees.
Doing it again, I'd go straight to TR6.
FWIW, the truck coils on my turbo LS, will knock your pacemaker offline!
