I got a Rotax 912 airbox here that's been buried under other stuff on the parts shelf for several years and it's finally worked it's way to the top. I've read/heard that it's not worth the cost/weight/trouble and have also heard that yes it makes a big difference in the performance. I don't want the 3.25 extra # especially up front but if it's worth it might install it. I'd like to hear the experience of those who have run it both ways and their recommendation. And any other valid info. I don't care about the carb heat; I've made it 10 years w/o it. (Zenith 701) Thanks JS
