In all honesty, Bill, you'll find argument either way. There are some people who swear by it, there are some who say they're worthless and its all in your head, and people in between both camps.
Personally, I'm willing to try it if it smooths out my idle and helps with my sensors. For only $20-30 in materials that's not a bad mod. I'm not entirely convinced it works (if it does anything at all, it seems to depend on the car), but I'm willing to spend the small amount to give it a shot.
