They are mostly frowned upon for the 4 and 5 cylinder engines.
Stick with the NGK/Denso/Delco Iridium plugs.

E3 Spark Plugs

what about the 5.3?
Of course, you have the V8. haha
I don't know to be honest. The 5-cylinder guys don't like anything but what I've listed. Can't speak to results of the V8 as they are altogether different.
Any reason why you won't go back with OEM? Or just want to do something different?
And are you REALLY due for plugs or again, do you just want to do something different?

well it seems that since i did my cam swap, every once in awhile it studders, i figured i would go ahead and swap out the plugs hoping to fix it and i figured why not its a fairly easy upgrade
oh and to answer your question, i had a friend that had the e3 in his dodge and he loved them but i know dodge and chevy are two different animals haha

Junk.
Get the AC Delco Iridiums.......thats what I'm running in my Tahoe

Just wondering, why do you say they are junk?
Nothing like shrouding the heck out of the spark. Pretty sure the E3s will spark in only one spot and the rest of the plug will foul.
Iridium all the way.

Thanks guys!
I wouldn't worry too much but either of the 3 if you decide to go that route. They all get about the same reviews. And 2 of the 3 are made by the same place, like AC Delco and Denso are the same or example. I'm probably wrong, but somebody will clear it up.
If you get the Iridium tips, do not gap them. They should be pregapped. If you attemp to gap them you can damage the coating making the plug junk.
I don't know why the GM V8 doesn't like them, but there is something about the design of the 5-cylinder that just doesn't play nicely with the E3 plugs (from what I've read, only).
Unfortunately the Iridium plugs are expensive and you have a bunch to purchase. I would think harder about the cost to possibly fix a miss due to your cam swap.
What you are experiencing isn't the nature of the cam is it? Do you know if fuel delivery is stable? Those are two things that come to mind for me.....aside from plugs.
Either way, a miss isn't always pleasant -I hope you get it smoothed out.

I was wanting to swap over to iridium anyways, as far as if the fuel supply is stable im not sure but i get the hesitation even in a slow, even acceleration so thats why im leaning more towards the plugs. but you are right it could just be the nature of the cam, not a big deal just thought maybe i could smooth it our a little.
Exactly what happens. I tried them and within 1000 miles one 3 of 5 fouled, they did honor their guarantee though and paid me back which I was surprised.Nothing like shrouding the heck out of the spark. Pretty sure the E3s will spark in only one spot and the rest of the plug will foul.

To the OP stick with ACDelco, Denso, NGK, or the classic Autolite coppers(these will wear out faster than most iridium and platinum plugs but cost almost nothing). Those 4 brands have never let me down though.
well cant argue with that, thanks man i'm picking up some ACDelcos tomorrow
i use the TR-5, one step colder TR-6 most mod motors on the Performance
truck site use them.

Is your miss always at the same RPM at different speeds?
By the way you describe the miss, I would look at a bad or cut spark plug wire possibly arcing accross something.
Ahhh didn't think about the wires, I'll have to check them out when I can get some time off to do the swap
As far as if it's at the same rpm idk because I never know when it's going to do it, it only happens every so often, I thought maybe it's the traction control and I'm just not getting the traction light on the dash, I say that because I don't have a lot of grip anymore with the stock tires
I just did plugs and wires on my Tahoe
AC DELCO IRs at .040 and MSD 8.5 Super Conductor wires.......very nice.

Coils and wires are sneaky. They're tough to troubleshoot because the failure can be temperature dependent.Ahhh didn't think about the wires, I'll have to check them out when I can get some time off to do the swap
