I changed the car's spark plugs at ~100k.
It's a 96 maxima.
Currently, it's @ ~150k.
Do I need to change them again?
How often?

Thanks

 

What plugs did you put in? If NGK platinums I wouldnt worry about them just yet. Platinum plugs good for 60k+

 

This is just me I'm sure other's opinions in this forum will differ. I changed mine @ 100k as well, I now have 135k miles and I don't intend to change them again until I either have starting issues that are spark related or 200k miles, whichever comes first. Just do your PMCS and your Max should last a long time.

 

k thanx guys.
yeah they were platinum...
NGK

 

yea you got alittlw hwile longer left, just keep on using them, they are kinda exapenciv for the platniums. drive alittl further then replace them again.

 

I think 100K on a set of NGK laser platinums is pushing the envelope. I have 63K on my original plugs and the car still runs like new.

I have no intentions of changing them unless I notice a reduction in gas mileage or performance.

 

could anyone give me a good write up on how to change my spark plugs

 

check the stickies
