A: It's not really going to boost your 0-60's or your HP's really at all if your bike is straight stock.

Q: Hows durabilty of the UM Aluminum airbox?
Over 8 years ago
I have HRC cam and jet kit installed on my 2004 Honda TRX450. The Um airbox requires re-jetting. Is my HRC jet-kit good enough to run this air box? I have heard conflicting stories about these aluminum air boxes ie... brackets braking constantly or not fitting properly. I have heard stories that people actually remove the aluminum air box because of problems. What is your opinion of the air box?

A: I've never heard of any complaints with regards to the durability or longevity of these aluminum air boxes, so I'm not quite sure what to tell you on that one. Seeing as how these air boxes are made out of aluminum I can't imagine that you would ever have an issue with them breaking (unless of course your bike is wadded up or ends up kart-wheeling down a hill or something, in which case I'm sure your air-box probably isn't one of your biggest concern any ways....haha!). As far as the jetting of your bike goes, getting your bike tuned properly to fit your specific bike setup (including any motor mods, intake, exhaust, weather, temperature, elevation, etc) is unfortunately something that I cannot help you with. Jetting (and tuning in general) is dependent upon so many different factors, so I hate to say it but there is no way I can make an accurate-general recommendation for you regarding how you need to re-jet your bike.
