i'm running denso iridiums
they're ok... i think launch control likes to eat plugs tho...
I had denso iridium plugs in my car for ahwhile. The car ran OK until it fried them within 10 months. I've got Bosch Platinums now, and I'm planning on sticking with them.
Bosch spark plugs? UGH

No way. NGK has been a top manufacturer of plugs for decades. They are widely regarded as the best in the business. The Delco Irridiums are supposed to be good but I would still go for NGK if I needed irridium plugs. The fact is if your car wasn't designed for them you don't need them and are throwing away money. My bike uses irridium plugs because it revs to 15K rpm and has 12.5:1 compression. That's the type of engine that needs them.
I found the best performance in my Talon (as far as plugs go) are plane-jane plugs replaced once a year or so. Irridiums have longer staying power but at 6 or 7 times the price they are not worth it unless you NEED them.
If you want better spark look to your ignition system. If you want the best plugs buy the right plug in the right heat range from a reputable manufacturer and make sure they are handled nicely. A dropped plug can lead to big ploblems.

Oh yes way,this is exactly what I heard,and Delco has been around alot longer than NGK.Although I would buy NGK before Delco.Many J's here are running plugs not designed for their motors,why not spend the extra money on a better performing plug

gm did not sell ac delco to ngk
gm contracted ngk to make plugs under their label
ngk is the sole provider on ac delco plugs currently , and the plugs used are the irridum which replaced the platnium plugs
ngk and ac delco , are going to be the best plugs to use
i had autolite xp's.... they chewed holes thru themselves.. almost lost one tip into my chamber.... :/ that was only 3 months of use... DONT BUY AUTOLITE... i know everyone bashes them.. but i heard from a little bird that the xp would be better.... NOPE

yeah they we gap right. i checked them when i put them in and when i took them out. right now i have the bosch 2 in there.
I've always liked NGK. The only reaon I have bosch platinums is because thats all wal'mart had at 2am and my car was missfiring badly with the autolights I put in it. The car seems to like the bosch platinums for some reason so I just left them in there until I can find some regular NGK's wich apparently are hard to come buy where I live. All I can find so far are the "gimmick" plugs like the V-power and so on.....I wan't just regular run of the mill NGK copper plugs. At least the bosch pulgs work OK until I can find what I wan't. I might have to order the things.

i put autolite xp'sin my stratus. the car runs alot better now.
not saying anything but, just because yourplus get burnt up doesn't mean there is anything wrong with the plug. could be anything, such as too rich of a/f ratio, cheap wires, improperly gapped, etc.
