NGK seem to work too, haven't personally ran them but have seen others who have.

STAY AWAY FROM NGK

AC Delco is OEM
e3's are upgraded. I use e3's there fine. I recommend them. I don;t know why some members had problems with them. Maybe they dropped them and closed gap? I dunno.
My truck fired right up with them in it...compared to the trun key...starts turns for a lil and then catches. (My starter just has a lil over 11k on it). When I did the e3's it started right up as soon as I turn the key in the ignition.

for the record, NGK is making AC Delco plugs now,
i prefer the stock delcos personally, stick with what works.

I'm getting ready to do a tune up on my yukon. I'm planning on ngk tr55 plugs and delco wires. Rock Auto sells model#718q wires for $107 and #9718q for $64, is there a difference? Also, does the brand of rotor, cap, pcv valve, etc. make much difference, should I stick with Delco or are cheaper brands fine? Thanks for any help

I would stick with AC Delco but that is just me.

Well I'm running NGK platinum plugs in my kon now, its been running NGK copper for about (well it looks like they haven't been changed in about 250,000km (about 150,000miles) before problems occurred). I dunno I've always trusted NGK.

And the last two aren't as bad as everyone makes it out, I actually had more trouble with one in the middle lol.

The delcos worked great in the truck but then again when I changed them everything looked like it was factory so I guess anything would have made it run better.
