E3 Spark Plugs?
Well, it's that time! My 05 has 45K on it and I'm going to change the plugs. I was watching speed TV and they did an impressive spark test between a standard plug and the E3. It was remarkable how the E3 out preformed the other plug.
Has anyone used the E3 before and could you share your experience? Do you think I would have the same "charging challenges" as the other folks?
Also, I'm adding headers, cat back, and CAI. Will this influence which or what kind of plug I should use?
Any feedback would be much appreciated!

I installed E3 plugs in my pickup. Can not tell any difference between them and a good platinum plug. No difference in MPG or anything.
I would not waist money on them again.
As for your plugs - why change them? The plugs are good for 100,000 miles. 45k is no reason to change them unles you just want to spend money and time.
If you are going to change them, go with the stock A/C plugs that it came with.

I want to change them because they have 50K miles on them, the headers are off, so they couldn't be easier to change, and I'm making other proformance improvements. Why have the plugs be the weakest link?
Would you not invest the $40.00 and replace them now?

Aftermarket plugs are not only a waste of money, but can cause issues with the charging system and random misfires. There is no reason to switch from the factory AC Delco Iridium plugs for any reason in a stockish built motor.

You are just wasting your money. There will be no performance increase or gas milage increase. I will tell you that you will see no benefit with switching out your plugs. The plugs have nothing to do with being the "weakest link" as you call it in your post. More than likely you will just end up breaking a plug or wire or mixing up the firing order. Don't create a potential problem when you don't have to. You can change your oil every 100 miles too but that doesn't mean you are making anything better. I would leave as is but do as you please.

if they were so great, how come NO manufacturer of high end sports cars, or any sports cars, use them ???

Do a search and you will see plenty of feedback from people that tried them and had problems.
I agree with the OEM plugs as a replacement and agree with you (OP) at 50K they are worn enough to warrent replacement while you have everything out of the way.
I run NGK's and have 0 issues but have read plenty of threads where people had issues with the charging system so I am actually considering going back to the OEM plugs when I do my cam swap.

You guys ROCK! Thank you for all your advice and I'm definitely going to stick with stock.
I already have the wires disconnected and I will kick myself later if I don't just change them now.
Be easy, fellow C6ers
