If there has been no mods to the car there is no reason to go with anything other than the stock replacemment. whatever you go with, be sure that when you take the first plug out that you compare it to the ones you purchased to be sure they look the same. One time on a trip to autozone I didn't notice the guy behind the counter ignored the fact I told him I have aftermarket aluminum heads and the plugs I needed plugs for it, and looked up the stock replacement grabbed them and acted like he did what I told him. I didnt double check and then I struggled with plugs fouling out for 6 months before I finally once again looked up what was recommended for trickflow heads and went and got them. When I compared the plugs I realized that the stock plugs are shorter/less threads on them so it was not completely in the cylinder being not long enough.
