I am not familiar with the thunderbike kit you mention. Is it a gauze filter like K&N or a foam filter?
BTW, I did not say anything about voiding warranty, I said the dealers will not work on the bike as a warranty problem unless the bike is in stock form. Huge difference.
As for money, I am sure some cone filters can be added to each throttle-body for a pittance. I went the way I did because I wanted to free a restriction, to hear the intake pulse, and it did not change the look of the bike. Seriously the sound is unique. Oh and on hot days when the bird is hot you occasionaly get a cough through the intake that gives a good tap to the jewels. I did not appreciate that sensation and it is no longer an issue. You combine this with the PCV and Autotune and it enables the next step, a custom 2 into 1 exhaust I am welding here in a bit among other possibilities.
