I am using the NGK Platinums right now. No noticable improvements. They were on sale so no extra money over the stockers. I will use the regular NGKs next time.

I expected to get some kind of inprovement, some where..since the originals had 30K on them. I'm cosidering changing back to the stockers some saturday when I am bored just to see what happens.

I put the bosch+2 in, right before my 4200 mile trip to FL and back. All I noticed was a better idle, as others have mentioned.

I as well noticed a smoother idle. But it seems i might have lost a little power to compensate.

I have used Bosch Platinum plugs for all my vehicles from an '86 Buick Century to my '03 Renegade. Just today I installed new Bosch +2's, and like other posters here, I immediately noticed a smoother idle, however I also noticed better acceleration. Nothing to write home about, but a noticeable difference. I upgraded from the standard Bosch Platinums.
