Are there any good aftermarket coin-on-plugs?

If it's any help...
I replaced mine with MSD coils on my F150 (5.4 2V) at about 80K miles since two of them quit and they have performed flawlessly ever since.
2 years later and 126K miles on the truck now.
Gas mileage was improved as well and it was cheaper to replace everything with MSD than going OEM again.

I also agree that Accel is junk, that product just doesn't last.

Granatelli also makes them.
Worthless POS.
Accels, the same.
Right up there with the BBK replacement
Throttle Bodies
that cause more problems
than they are worth.

Sorry, I lost track of this thread. I have the originals on the car now and I'm getting a misfire under load. No codes, but it feels like one of more cylinders aren't firing every time, in other words it feels rough, not smooth like it used to feel.
