It depends if it is the original plugs. Did you buy the car used, do you know whenth plugs were replaced last time? You could always pull one plug out and check for condition and measure the gap. I use NGK plugs from parts store.

I like Iridiums, cheaper than Pt's, last longer, and smooth the idle out.

I use NGK iridium as well. Very happy with them.
