Time to change spark plugs... AGAIN?
I recently took out my spark plugs because the car was running like **** and sputtered when I put my foot on the and misfiring really bad. I took out the spark plugs and to no surprise they were in horrible condition.
I bought some NGK spark plugs from advance and it was running beautifully for about a month. Now it's doing it again... and I don't know if it's because the spark plugs I bought suck or because something is causing the spark plugs to go bad so quick.

Sounds like there is something wrong, like running rich, lean, oil in the chamber, etc. causing it to foul the plugs so quickly.

Yea I've seen this chart before.. I guess the only thing left to do is pull the plugs and see the condition it's in. Anything I should be looking for other than the condition it's in once I take it out?

i don't know about most on the site, I changed my plugs every oil change...
doesn't mean that something isn't right but I also used meth inj as well.
is it just one plug? all plugs?
what color are they, black / white
what fuel are you using? stupid question I know, gap right?

Well,
im glad you think so
once again reading is key, aparently you do not use meth injection?!
if you look at my build, I was not using cheap o plugs but I just found out that meth likes to eat plugs so it was just a habit I got myself into. I didn't recommend to him he needs to do it, it was something I got into a habit of. I know I could have went another oil change on them but what the heck right
I also had an aggressive tune and running 30lbs of boost daily maxing out my setup
I was okay with spending the money on spark plugs to not have any issues

Have the car tuned for Iriduims, in a colder range. I ran coppers for a year, and went back to Iridiums. The driveability is much better, and they do last longer if you are daily driving the car.

Ugh.. sorry I know I'm kinda late just been really busy with school and work. Uhm they're white irridiums and they come pre-gapped. I just got the ones advance carried because the ones that were in before were so bad not sure of the specs but I think the heat range was the same too.
I made another observation today though. It doesn't happen in 1st or 4th gear. I haven't had enough space to try it in 5th but apparently its just 3rd and 2nd. Could that mean anything?

You can gap iridium plugs. Just have to be careful. If the gap is too large, lightly tap the plug on a metal surface, I use a socket. If the gap it too small, carefully open it up with a pair of pliers.

What they told you to buy.

However depending on your power upgrades, you may not need the plug I suggested.
Stock equivalent in Copper is a BPR7ES.

What are the mods? Anyway you can get a nice "Macro" picture of the plugs?
