Perfect example of todays SNAKE OIL SALESMAN. I am always surprised at how many people can be fooled by outrageous claims. You should all save your money for a computer chip or something else worthwile, because unless you're going to spring for a turbo or supercharger, all you're going to get is smoke and mirrors. K&N have made the least outrageous claims, and at least other than lightening your wallet by about 60 bucks, they do no significant damage.( They also don't add HP). Some of this stuff is just plain silly.
