It seems that all aftermarket plugs are too short and some up to 7mm shorter than stock which is not good, whats worse is places like autozone even list them as being compatible. Is there a stock sized plug out there that is copper?

No i dont think so i have looked and looked. I have a head on my bench and screwed in some NGK tr6 that a lot of people run and it puts the spark way down in the hole plus leaves about 3-4 threads with nothing in them.
I bought Denso Iridium ITV20 which is correct lenght and 1-range colder they are more heat resistant than platinum BUT PRICY AS HELL.
rodimus I am telling you the 103's are fine...

I went to a Saturn dealer and was going to use the same plug that they run in the Ion red line.Well the plugs came and they are a Non taper seat type plug (gasket Washer).So I,m still looking also.The problem with running a shorter plug is that it retards the propagation of the flame front across the cyl. And those bottom threads for the spark plug become pluged with carbon and if you want to reinstall a stock length sparkplug you may damage the head. Plus Saturn wanted $29.00 / plug.I think a set of the Denso,s is the way I,ll go.
Thats Him Officer The WICKED One.
the 103 is 7mm short thats not ok by any means, denso is crap i had them and they are all used up after 20k

i never had any probs out of my tr6's when i was spraying.
Yea the Redline and the turbo Saab motors take a shorter reach-gasket style plug so that wont work i was trying to come up with a way to remachine the head for the Saab style plugs--there are tons of heat ranges and styles But have not come up with anything-You can do them on a milling machine but i wanted to try and do them on an assembled engine. Those plugs are 14mm, 750 reach with gasket-stock are 25mm long taper seat. There is a Splitfire in the right lenght but i can find a cross over for heat range and it only comes in 1-range BUT YOU MIGHT CHECK THAT OUT

thats BS dude.
i run densos for over 46k, and still have the first set i used, AND i run msd, which is way more spark than your car stock was throwing in and prob still is.
might need to do regular maintainence and tune ups on time.
never run less than the 25 mm, if that was the case, gm would have put in a different plug in each cylinder
would you like to see the plugs ? Tune up my ass theres nothing old on that car

a more complete tuneup is to be done atleast EVERY 30k dude. however there are smaller interevals located within the manual that came with your car in your glove box.
i really dont need to see the plugs to know iridium is harder than platinum. with that being said, if you are running hot and or with incorrect gap, i really dont see how you are running through plugs in 20K on a stock ignition.
tuneups have nothing to do with being old, and you car does have 70K on it. every oil change is 3000 miles or should be, when you go over, you tend to run hotter. oil degreades and breaks down. doesnt stay as cool when it does this.
when you plugs wear down a bit, regular maintainence is to regap them.
theres normal maintainence thats tunning up your car. and if you dont do it, i think it goes without saying things dont last nearly as long.
like said, people running way more to and through those plugs are lasting twice as long. you just got boosted, so you really only had basic boltons.
and we know you slack on maintainence a bit, even this saturday you said the noise in your power steering pump was due to lack of fluid, and i told you to check the fluid months ago, even offered to check it for you one night before leaving denny;s.
The car has never gone past 5000 miles on an oil change that was once, the plug could not be regapped as most of it was missing, its a wonder I was even still firing on that cylinder
Copper plugs are what is proper for boost

thats my point right there on maintainence.. just cause synthetic oil may last 5000 miles, the filtration of the filter normally doesnt.
and thats fine if you want copper plugs no doubt,
but whats proper isnt just limited to one thing. like said, i can count more people locally in just towson alone, running a hell more boost than you have currently and run iridium. but they also do maintainence almost god like. i change oil and filter at 2700. with these guys running 13psi+ they change at 2500.
g'luck though
I told you rodimus, how many freakin people use 103's and NO ONE has ever had a problem...

I run Denso Iridium one stage colder (25mm) OF COURSE. and they are bad ass. They work well when I run 10 to 18 psi of boost. I dont know why anyone would want to put in a shorter plug than recomended. That is ridiculous. If your going to spend the money on a turbo, dont half ass it with the #1 thing your ignition depends on. Especially since air/fuel is the #1 priority tuning part of the turbo. Are they expensive? Yes. But at least you only have 4 cylinders.

attn idiot: according to denso, one plug is made for us to fit the ecotec, and is still 7mm shorter then stock,

WOW I DID A 30 SECOND SEARCH FOR AN ECOTEC MOTOR AND LOOK WHAT I CAME UP WITH. A 25 MM DENSO PLUG SPECIFIED FOR THE ECOTEC.
YOU WERE SAYING???

hes right, most all denso plugs come in heat ranges hotter and colder (length of the insulator nose in the plug). if you need a special lengh just call em, they can let you know what satisfies your needs.

not saying hes a retard, hes done quite a bit since beginning here, no doubt...
but since rodimus must have copper and denso to him is crap, its pointless for you two to discuss it. unless you wannnna.....
matter of fact matt, please post a picture of your denso spark plugs, you can tell alot from them and whats up with your car. it would definately be a tell-tale of whats up with your engine. a close up shot of the problem area would be nice.

The Denso plug has 20k miles on it, The AC Delco 27k, The AC Delco looks almost brand new where the Denso looks beat to hell. Notice the Denso missing half the part under the top, the ac delco again amost brand new

seems like you need to start doing maintainence better.
heres my plug

i sincerely doubt the stock gm ignition throws a larger or a longer spark than the msd does.
50 K on msd vs your 20k on stock.
injector cleaner should be every other or every oil change for best results.
matter of fact from their site and how to read plugs, it almost looks as if the area above the threaded part thats white and says denso....
it pretty much looks like they werent torqued to spec and seeped combustion out of the chamber. theres no reason it should be THAT dark under where it says denso near the top of the picture.
Once again wrong all plugs looked like that amazing my Delcos never did
I still dont know where your getting this maintainance thing from I maintained the car better with the Densos in than the time in which the delcos were in why they in such better shape after MORE miles, simple Denso is an inferior plug that is not proper for the application, keep in mind your also comparing a 2.2 to an eco not even the same plug or engine
