Best Spark Plugs?

[Erik G]

use the ac delco's but check them carefully before you leave the store. I did mine this weekend, 1 cracked straight out of the box, another there was something not quite right with the cap. It wouldnt seat the spark plug wire quite right. They replaced them right away but kinda a pain in the ass to go back twice

I've used AC Delco 41-110s but have also heard the NGK 4177/TR6s are also a good option.

What should the gap be these plugs? I have a 07 burb

You use the iridium above and don't touch the gap

From my old car work that seems stupid but it is how it's done with modern cars

I usually check them and keep them close to .40

Anybody know the part number for the iridium plugs from Rock Auto? Thanks in advance.

AC Delco 41-110, look under the plug section, lowest section titled iridium.

Just ordered a set. Do you advise changing the coil wires as well? I do have the p301 code. And a little rough idle with minor cutting.
