If that was true, everyone would have one.

the cover will give you maybe .05hp- a good air filter will give you an additional 1-2hp max but a whole lot more sound + some cool looks-

Looks only....imo, waste of money unless you are into decoration.
BTW, the 'good' air filter is the stock paper filter.....the popular 'oil' filters (once only sold as racing air filters) let in fine dust/particulate matter...the paper does not. I live in the Az desert, I've seen the dust/dirt under a well maintained oiled mesh gauze filter that does not exist when changing to a stock paper. I was getting my carb dirty and the idle jet blocked using one.
