Ok,
I have used both! In fact, I have the TNT tubes and cone filters sitting in my garage. There has been much debate as to the effectiveness of those intake systems which take the air in down low(more heat) and make the air change direction. There also has been a debate about a Carbon Fiber airbox adding anything over a stock one with the Rain baffle removed. If you do a search on this site, you will find several posts arguing this very subject.
My conclusion - go with the one you like the best, looks, gut feeling, whatever. They will both add performance. If one offers 5 more horsepower, will it really matter?
Best of luck!
Regards,
