yeah sorry i had to PM you as it was too long of a message to type here.
The first link you sent me would honestly probably hurt performance a lot, would be worse than stock. This is because the filters are open and would suck the hot air from under the hood. The second link would be better as it would be mostly sealed once the hood is closed and draw cooler air. The best design (IMO) would be a fully closed one though, I believe volant makes one, it has a silver top, sort of trianglish shaped I believe.
