Probably wont notice it. I think what the claim is, is that they restore a potential 6 hp, not add. So this is only if your plat's are so bad that you've actually lost 6 hp. I put Iridiums in mine just about 4K km's ago, they are nicer, and I'm happy, but I have terrible engine lag so I've never been able to tell whether they felt like they restored power or not. If you can get a good deal on them, they're a nice plug, otherwise, platinums are probably going to be just as good!
