Do a forum search for spark plugs. A bunch of different types have been tried, but more often than not the stock AC Delco seem to work the best. Gap does make a difference. .032 seems to be the most common gap with the most success.

So the other night I had a misfire again and then a check engine code came on. P0301. Which was a misfire in cylinder #1. So I decided to pull the plugs and check them. WOW! They were all pretty bad. I replaced them with NGK Laser Cut Iridium OE plugs. The are recomended as OE replacement plugs for the Solstice GXP. The factory plugs are crap! Autolight plugs are around 2-$3 each. The NGK Iridium plugs are good because they are a hotter running plug, better for the turbo LNF-5. They cost around 9-$10 each. So basically you get what you pay for. After installing these plugs, the engine started right up with no hesitation. Rough idle is gone and car runs great! My boost went from 14-15psi to 16-17psi. I understand that the turbo 2.0 goes through plugs pretty fast, but after only 21k miles the durability of the stock plugs just doesn't last. Seems like Iridium and copper are best for high performance engines and turbos.

unless the head has a threaded metal insert cast into the head, NEVER take a spark plug out of a hot aluminum engine.

Well.....I've had to many times at the track with no issues, but probably a good rule. And never fail to install plugs in any alloy head with a dab of antiseize!

sometimes ya gotta do what you gotta do... but it only takes one time for the plug threads to start to seize and peel out the thread in the head.

Guys, I waited a few hours for the engine to cool down before I pulled the pugs. I even disconnected the battery before I began. Not sure if that part was needed, I was being safe. And yes, I always use an anti seize lubricant when installing new plugs.

You get what you pay for. Cheap plugs suck. Sorry.

Yeah, I know what you mean.

It really P's me off when someone gets a super deal that I didn't find and paid WAY less for them. Especially when it's items such as spark plugs that the factory used when they dyno'ed the lump after designing it.

Plus they will keep any questions about my warranty out of any discussions at the dealer.

YMMV!

I am a little confused. I thought boost was determined by the maximum limit set in the tune, the temperature, and elevation. How would better spark plugs give a higher boost.

Sorry but they do not. This is your opinion and so far there has been ZERO issues with the OEM Delco plugs.

You're correct, but the stock plugs were so bad off that it was making the car run like crap.

Be that as it may, the plugs got that way for a lot of other reasons none of which were the designed of the plug.

Dealership says it's fouled spark plugs. I bought the recommended spark plugs, AC Delco 41-108 because these have better cold starting characteristics. Went home, waiting for engine to cool down, installed new plugs. Still same results. Misfire at start up until car warms up, but no check engine light this time. Still has "shudder" at idle speed.

Can't afford to go back to the dealership right now. Girlfriend just got laid off last week so money is tight now with just one income. Will have to wait another 2 weeks until I get paid again so I can just leave my car with them and let them experiment with it. I still think it's the fuel injectors.
