Platinum spark plugs?

[roadrunner]

I've used the platinum plugs as an OEM replacement, mainly because they last so long. You can just drop them in and forget it.

Bosch (and others) is pushing their "plus 2" and "Plus 4" multiple gap plugs as a performance item. Bosch guarantees you'll notice a difference or they'll buy them back.

I'm a little skeptical (unless you're replacing a worn/deficient plug). If anyone is running them, have you noticed any difference in performance or mileage that you can attribute strictly to the spark plug??

I'm running the Bosch +2 plugs and the throttle seems a little more touchy...by little I really mean LITTLE...only good thing about them is I'll probably run them for almost as long as I own the KJ. Would I buy them again...probably not.
