yeah the title says, when do I need to change the spark plugs in my car??? Also lately when I turn my car on, it idles rough going from 1200-1300rpm or is 12000-13000rpm I forgot lol.

 

1200-1300RPM... And most spark plugs don't need to be changed for many many many thousands of miles. Like 50,000+ I think the owners manual says 75,000... somewhere in there. And you aren't running under boost... so you shouldn't have a problem with your spark plugs not lasting.

 

1200 to 1300 RPM... hmm...

I changed my plugs at 10,000 miles... went to the NGK BKR7E's... which are just copper plugs so you need to change them regularly.

Are you still running on your stock plugs? How many miles you got on the car?

I know it's not a SS/SC... but plugs are cheap and you could probably benefit from a new set.

 

change my every 8000-10000 miles too good rule to go by

 

plugs are like oil.
you can run them as long as they say.
but it never hurts to give your car fresh oil.
or fresh plugs.

 

Plugs are also like oil in that it's easy to check them for signs of wear, and as long as they're not fouled or worn, there's no real reason to change them.

 

checking them is good since it keeps them from seezing in the cylinder head. Or go ahead and get new ones they arent expensive.

 

yeah... if you are gonna bother with checking them... might as well just replace them

 

the car has 22k miles on it.

 

Do the plugs make a diff. in performance? I just got a stage 2...

Are they hard to install?

Tagging

 

with my few mods should i get a step colder plug ......... high heat climate and daily hard driving is why i ask ?
would it damage the car to get a step colder ?
