but performance/milage wise i won't see a difference since i'm onyl @90k right?

In theory your plugs are 3/4 worn. Actually you won't know unless you take one out and look at it. Depending on how the car was taken care of and driven you could be good for 30K more. Or they could go in 1K or less. Are any miss firing now? Does your car shake at idle? Any CEL's?
