I've heard lots and lots of conflicting opinions on this matter. Some people say if your vehicle came stock from the dealer with copper plugs, then you should stay with copper plugs. Others say platinum/iridium/etc will last longer and provide a better spark..
What do you guys think?
In my old Intrepid I used to run quad tip platinums, until a guy at autozone told me that not only do you not get any performance increase from them, but, due to the four tips, they can actually screw up the air circulation inside your motor and hurt performance.
Now I'm not sure if I really believe that quad tips can hurt the air circulation or not, but I do believe that they don't provide any performance increase.
But.. I'm wondering what you guys run? I'm about to go buy new plugs, I've been burning through amazing amounts of gas lately, and I pulled my plugs today and they were COOKED.. missing metal, burned, looking horrible. I've never seen plugs this bad.
So should I buy platinum or some other kind of higher end plugs, or just stay with the basic coppers?
