i had a bad experience with cheap plugs.. they keep on going out until i bought NGK iridiums for 32$ for all 4 , and now ive had them for 6 months with no problems

 

i dont know i did,lol

 

lol ^^^
it sux driving like that cause its even slower

 

yea get those. Dont be like me and go to advanced auto and get magstar racing wires for $60 .

 

Its all up to you on what kind of plugs you get, although I dont see how spending $9 more on the iridiums to have them last longer and work better is such a huge deal to everyone.

 

wow $60

 

It's not great for the car, but I doubt you'll ruin anything. How bad is bad? Is it working or are you running on three cylinders?

There's more expensive choices...

 

Copper plugs perform better FYI.

Electrical conductivity:
Copper's conductivity- 595.8 1/mohm-cm

Iridium conductivity- 188.679 1/mohm-cm

Platinum conductivity- 94.34 1/mohm-cm

 

The check enguine light is on an i went to autozone, and when the plug the lil computer it said the 3rd spark plug was bad.... but when i use the car it make the cold air intake make a weird noise, an when at a red light it starts to shake alot an i keep it reving low so it can stop shaking

 

dude, stay off the drugs and speak in english.

 

Perhaps you should have bought a new spark plug since you were already at AutoZone.

 

Very true, I guess im just used to using a step or two colder for my turbo setup.

 

Nothing wrong with iridium or platinum. Well, technically. They are "stronger" and that is why they last longer than the copper. If you are pushing really high boost most people will recommend copper plugs ALL day long. You would be suprised the difference between the most expensive iridium and the cheap copper core. You should try it to see if you notice a difference (they are only $1.50 so it couldn't hurt lol)

 

If you're gonna go copper, get NGK V-power. That's most likely what came in the car from the factory. Whatever you use, get some anti-seize. No use in buying cheap plugs that you have to change more often if you have to wrestle with the engine to remove them. I have NGK Iridiums and I like how smoothly they idle. To most people a little bit of idle smoothness is no big deal, but I have solid motor mounts.

 

A. V-power IS the copper plug.
B. Copper will idle smoother than iridium
