Depends how the the tune is working out for his car. He may have fouled the plugs if the tune was ****. Even if he's stock I still wouldn't trust the tune. The canned tune from the factory is ****...

 

Also i race the car weekly at the track in the summer, i wouldnt trust the plugs to last that long lol

 

Alright, talked to the ac delco rep that comes in to our auto parts store, hes going to get me a set of ac delc iridium plugs for free. On the delco website it says not to cap them though... Most places i read keep saying in bold letters not to gap iridium plugs. So if i get them and they all look identical for gap, im not going to mess with them.

Also i dont need to use any grease or anything when putting in the spark plugs do it? when i took my current ones out, there wasnt any grease or anything

 

Dont use any grease its not needed.It says not to gap iridium cause of the fine center electrodes.You can break them off.If you have to gap then then use needle nose to bend the ground electrode out

 

I personally would take the 5 minutes it takes to set the gap properly. Just my $.02...

 

exactly... I learned that the hard way... I broke a $13 iridium plug trying gap it the old fashion way when I was putting plugs in my motorcycle..

 

when talkin to the rep he says gthey are shipped ina box and spark plug has a hard plastic shell around it to prevent any damage if dropped during shipping so he said theres no need to gap them

 

The Koreans are like the Federal Government but IMO...I don't trust a damn thing they do

 

hes white lol

 

NGK's

 

I didn't say anything about the wholesaler but I'll guarantee that the spark plugs were made in Korea or Taiwan or some **** hole place like that with people getting paid $5 a day. Just saying would you trust that **** or would you want to double check to make sure it's right before you put it into your $20,000 car?

AC delco professionals.

they're cheap, they're iridium, they're OEM, what else could you want?

 

What do the one step, two step, or even three step colder plugs do? HP gains? What is the purpose?

 

not for N/A applications so doesnt apply to my thread

 

a very very simple answer... a colder plug can take more abuse, but doesn't burn as cleanly when used lightly. so, what happens is, as you crank up boost, or add spray, sometimes one or two notches down the scale allow the car to run correctly.

no plug can "add" power, it's more of a getting the right plug so that the engine you have runs correctly. and, IMO, it can be as much of a trial and error as anything else. i've seem some bad ass turbo motors that ran best on stock list plugs, and i've seen some stock engines that needed a range colder to run right.

if you run your car hard a lot of time, or run it for sustained highway traffic, it's not a bad idea to try one range colder. being N/A or boosted has nothing to do with it.

also, forget what else you read, all other things being equal, copper plugs are the way to go. iridium is growing on me, but i've yet to have good luck with platinum plugs.

 

All the info I needed! Thanks!

 

I have never had any luck from a platinum plugs.. I have been using iridium plugs in my built 4.3 S-10 for almost 2 years with no problems.. Iridium plugs seem to hold up better over copper plugs to my MSD ignition system.. platinum plugs never have performed well for me.. I guess its were they require so much more energy to spark..
