What is the best intake for my truck as far as power gains go? I've looked at KN, but their chart only showed a 12 HP gain. Is their anything out there better than that?

 

The numbers are pretty much the same across the board....but find one at a good price thats a different story...

 

I've got a friend with a Ford 5.4L and he has an AFE intake. I'd never seen one before until then. He reved it up for me and that thing really pulled some air in. He said he got a 15 HP gain, but he may have been bluffing. He even has a spot under the hood where the intake keeps it spotless.
