if they are stock replacement items I would plan on a tune up.

They might make a big difference if they havent been changed in a while. i am no english expert, but i believe it is " CURIOUS"

I think you're supposed to change the wires every 3-4 years for good measure and I personally change my plugs once a year. A lot of people like the 'ol Autolites, that's what I have in right now.
