Reliable replacement brand ignition components?

I have bought US made parts recently that are the same quality as chinese 10yrs ago.

I agree, which is why I look for NOS parts that aren’t recent.

After installing the DUI coil and ICM my throttle felt a lot crisper. Dunno if it was a placebo effect or if it actually made a difference; either way the OE coil was absolutely on it's way out and the ICM probably wasn't fairing too well either. I just hope putting their distributor in will make a big difference too since I'm 90% certain my OE dizzy is probably worn, over 200K miles on the truck now and it's never been changed.

If by DUI you mean SMP Blue Streak coil, I recall a mechanic say something similar about installing Blue Streak coils in the Gen 3 5.3 trucks.

He’s talking about these guys.

So I just realized my original coil is riveted on?
You guys who have replaced your coils, did you just get some hardware store hardware?

All the gm coils I’ve done have come with a hardware kit. But it’s just machine screws and tiny nuts

My original icm was from Singapore, I think.

LOTS of GM HEI modules were made in Singapore.
