Default Best plugs for a 99 5.7 Vortec in a suburban

Any input for plugs and heck cap rotor and wires?
I normally hang out on LS1Tech and now that I have this ride I guess I'll be hanging out here as well. Are some NGK's a good option? Any input is appreciated if anyone has some. What about that Accel tune up kit they sell? Thanks.

I'd go with NGK or Delco on the plugs, and Delco on the cap, rotor, wires...

In my experience, the only products Accel makes that the L31 Vortecs like is the billet aluminum distributor housing, and even that for the most part is for the cap screw mounts that don't get torn out since they're metal and not plastic composite.

For cap and rotor, can't beat AC Delco for quality, fit and durability. Distributor housing too if it needs replacing, its a toss up between Delco and Accel's aluminum like I said.

for wires I just picked up some 8MM AC Delco wires for my truck, they're VERY nice and I've heard are great on durability. Plugs, always and forever I will say AC Delco from stock to moderate bolt on, NGK TR55s for serious NA and NGK TR6s for any forced induction, always properly gapped.

Thanks.
