Ulmer tried some airbox mods but had no luck with gains, instead he used K&N filters and they have shown good gains..up to 5hp in the mid I believe. Hurricane Performance does an air box mod that works but in conjunction with a full header/muffler combo and his RB3 fuel map. Bullseyes on there own don't do anything from what I've read
