What the H*ll are you guys talking about??? IT DOES add rwhp, about 50! 
You must not be installing yours correctly!
o.k., o.k., that's
but it DOES do a good job keeping the engine bay clean

The Performance Version of the Hood Seal does work...
It keeps HP from leaking out of the engine bay... and we all know how
horrible it is to see used/lost HP, laying on the side of the road.
Personally, I stop and pick it up when I can... I'm not too proud to do it.

Just follow a Mustang. They leave HP all over the place. Bring a broom.

Now I've seen Nytes write up I just can't wait any longer.
Add this to the extra HP from the cooler winter air and I may just break Mach 1

No question about added HP, but you have to get your seal at the Home Depot High Performance/Racing Department, which is right next to the 200mph duct tape, to get the real benefit.

It also prevents water from getting on your filter if it is open...sure it is not a great deal of water, but I wouldn't want any water getting on my NOS solenoids I mounted in the front of my filter.

OMG, it just stop dirt and water from entering the front crack. It DOES NOT increase HP.
But the muffler bearings and blinker fluid do

Yes, it is but it does help keep the engine bay a little cleaner.
